Limiting a Great Receiving threat in 12/21 Personnel

12/21 personnel groupings present a number of stresses to a defense. The obvious threat is run heavy structures using big personnel with a TE/FB creating extra gaps in the run fit. Heavier personnels often induce loaded boxes and 8 man front structures from a defense to handle the run game. Those loaded box defenses can also create single coverage for a star WR. This can lead to offenses using those heavy personnels/sets to attempt to isolate their best WR creating passing opportunities off max pro, play action, quick game, or RPO concepts. These personnel groupings also allow for a variety of 6,7,8 man pass protections. What is the solution in regular down & distance situations? How do we stop the run while controlling the star receiving threat? Here is a solution from the 3-4 spaced defense using quarters and halves coverage principles. Putting a cloud on the star WR can be a really inexpensive solution to mitigate some risk.

The coverage concept combines two coverages: Stuff and Roll. Stuff is a 1/4 1/1/2 concept while Roll is a double rotated Cover 2 concept. 

The point is an activated OLB as the 4th rusher. The Mike will make a Rome/London call to activate an OLB. We are going to activate the OLB to the side of the star WR. 

Vs. 21


Against a pro set if the star WR is to the defensive right the ILB will make a Rome call to set the point. The point OLB becomes part of the charge. The coverage will play Stuff coverage against a formation with the star WR as a single X. Stuff means half tool to the point and a quarter tool away from the point. Structurally this allows the defense to be sound numerically in the box vs. the run while putting a cover 2 concept on the star WR to disrupt passing concepts. Here the quarter Safety must trigger to become the 8th fitter in the box when the TE blocks.



When the star WR is strong the LB again will set the point to the star. Here London is the call with the star aligned to the defensive left. London activates the left OLB into the charge. The coverage will be Roll. The coverage shows as cover 3 rotated to the point with a Safety down and a Safety in the post. Showing a middle of the field closed look helps dissuade the offense from attacking the middle of field based on pre-snap coverage presentation. At the snap the post aligned safety rolls the coverage to a cover 2 concept strong with an inverted cover 2 concept weak. When the TE blocks the vertical hook down Safety become the 8th fitter for the run. Again this concept gives the defense an 8 man front spacing vs. the run with a cloud on the best WR. 




Against a single width twins formation the coverage again rolls. This again builds the 8 man front. The Corner to the nub will align at 8 yards in the C gap if the TE blocks the Corner will trigger to become the 8th fitter. The coverage still places a cloud on the outside WR, if the star is outside we have a cloud on him. If the star WR is in the slot the coverage has a Safety playing the vertical hook. The VH matches the #2 vertical and inside with safety help in the deep half. With a safety rolled down into the VH drop we feel we can match up with a WR. If the #2 is out the cloud corner will be squatting in the flat. Overall with the star outside or in the slot the coverage can help deny that player the ball while still building the 8 man box.

Vs. 12



Against a 2x2 ace formation the point will gain be to the star. The coverage is stuff with a half tool to the point and quarter tool away. The quarter safety helps build the 8 man box while the cloud helps deny the star.



 Against a 3x
1 nub set the coverage is again Roll. The coverage rolls against any single width formation. The coverage denies the star outside or in the slot similarly to the previous twins example. The ILB does have the TE vertical to the strong side in a match so that's a matchup we are always mindful of in this concept.



A backside wing is treated like a single width formation and we will Roll all single width. The coverage again plays like the previous single width sets. This time the LB to the wing must be mindful of the VH responsibility against vertical passing concepts from the 2 TE side. The nub side Corner is again the 8th fitter. 


With the star as the single X the coverage is Stuff. Half tool to the point with a quarter tool away. Here there are 3 receiving threats to the quarters side. That means the tool needed must be a quarter tool for 3 receivers. In this example the quarter tool is a mini 2 concept with the outside WR manned by the Corner. Inside the OLB/ILB/Safety are playing a 3 over 2 coverage on the 2 TEs. The Safety in the mini concept strong must trigger when the TE's block to add the 8th fitter in the run game.

With the star aligned strong in the formation the coverage Rolls. The Safety shows post alignment rolling at the snap. The point ILB must be ready to match 3 vertical. The VH Safety is again the 8th run fitter then the TE's block in the this concept.

Putting a cloud on a good WR in heavy personnel can be an inexpensive way to both be good vs. the run and deny the biggest receiving threat. Much of the coverage concept is built from coverage tools that most defenses already have in the their toolbox.

Adjusting the Run Fit in Fire Zone Pressure

Fire zone has run fits like all other defensive calls. Those fits can be adjusted to help prevent issues or account for stress areas. 

Here is an example with a number of errors resulting is a good gain for our opponent. 


What were we trying to accomplish?

We called this pressure to have the DL slanting to the boundary with the walked up OLB on a low track spill course and the ILB going from depth on a wide track. This is a variation of America's Fire Zone. When the OT blocked out on the OLB the Sam should have gone under the block. The expectation is the Sam will go inside/under blocks because the ILB will be pressuring on the wide track outside. That is one of many mistakes on the play, the Sam stay outside. We also have an "I'm IN" or "I'm OUT" call happening here from the Safety. In this example there is a split #2 resulting in the down Safety saying "I'm OUT" meaning the ILB has the wide track.

If the #2 was in a cut split or a TE the Safety would have a better angle for the wide track and would call "I'm IN" taking the wide track pressure pattern and job swapping his seam drop to the ILB.


This is a run pressure concept, the angles can be beneficial to alter who is in the pressure pattern based on the formation.

Why take on this type of complexity? Why not just let the Mike be the wide track the whole time? Don't make it harder than it needs to be. 

On this call the #2 went in motion.


When the motion happened we didn't get the "I'm IN" call. The Safety should have gone from out to in with the motion. That plus the missed assignment by the Sam lead to the Mike's confusion. He gets caught in no man's land neither pressuring nor reacting to the play. 

The Safety ends up on the edge of the box playing like we don't have any "I'm IN"/"I'm OUT" rules on.  

Let's assume we did coach it with no "I'm IN"/"I'm OUT" rules in place. The Mike would pressure no matter what. The Safety needs to vise the lead block with the Will LB. The ask of the Safety here is very very big. The Safety cannot be too aggressive running into the box when he reacts to motion to avoid several problems:

1. Running into the off the LOS ILB wide track pressure from the Mike

2. Over running any potential run by the RB to the pressure side

3. Over running any potential route release from the RB or Y off

4. Over running any return motion from the #2

Just like in the actual clip the Safety ends up being too far from his work to fit the vise on the lead block and the run fit has issues.

If we had correctly handled the "I'm IN" call on this play.


Now the Safety has a great angle to hit the wide track pattern on the run as the motion pulls him inside and into the pressure. The Mike can shuffle over. The result is 2 inside LB's vising the lead block while the pressure pattern remains intact. The Mike doesn't have to be in a hurry allows him to be able to react to any flow or route threats to the pressure side. His stress is less than the Safety being asked run full speed to get to his work as in the prior example.

Something like "I'm IN"/"I'm OUT" may seem like unnecessary complexity at first look. That added complexity got us on this play as we didn't coach it or execute it well enough. You can choose to use that as strikes 1, 2, and 3 for why you don't need something that might create confusion. However, when executed correctly it relieves a great deal of stress on the players.

What is another option if I don't like the "I'm IN"/"I'm OUT" concept but I'm worried about the stress on the Safety. 

Another option is to set pressure Strong (To the Pass Strength) instead of to the wide field. 


In the original example the pressure pattern adjusted with 
"I'm IN"/"I'm OUT" but stayed coming from the field. In this concept the pattern is declared to the defensive right because that is the pass strength. This version has no "I'm IN"/"I'm OUT" rules and will always be an OLB + ILB pressure pattern. 

When motions happens the pressure is changed to the left.

The pass strength is now the left. The defense must now reset the pattern with a left declaration. The new pressure is well positioned vs. runs to the TE side. However, this does create stresses too. The LB's/Safeties have to communicate and adjust quickly to the motion. The DL must hear, understand, and execute the new left call in the pressure pattern. The rotation of the Safeties also creates stress to execute. Lastly, the adjustment also places some stress on the plays like split zone and counter going away from the motion. 

These two options are both tools to have and rep to help take some stress off the players when motions happen in the fire zone run fits. The set it and forget method works in some contexts but if the offense begins to stress those hard called pressures that don't adjust there are only really three options:

1. Make no adjustment and ask the players to repeatedly execute difficult tasks, this includes the player over playing to achieve the difficult task and creating other potentially bigger issues

2. Allow the offense to chase you out of fire zone pressure calls

3. Have tools available and understood by the defense to be able to adjust. 

It is easy to throw a cutup of good pressures on and say "see it works". Well what about when it goes wrong? What are mechanisms of failure? This post hopefully shows a failure we had in way that not only addresses how and why but also gets to the why behind adjustments we carry and coach. Having the tools available is the key to being a complete defense. It takes constant work and there will be failures. Those failures can fortify why we are doing what we are doing, to give players the best possible chance to succeed.  Simplicity for simplicity's sake and unnecessary complexity both undermine the goal. A clip like this one isn't fun because we failed on the play however it is invaluable for helping players and coaches understand the why. Good luck as you build your tool box and master your tools.

Giving the Corner Relief in Isolation on the X in 3x1

When the Corner is isolated on the X on the backside of 3x1 formations it can be nice to find calls that help provide that Corner some form of help. In our defense we call these concepts relief calls. 

Here is an interesting example of a relief concept from the Ravens. Baltimore is in a Nickel personnel with 2 OLB, 3 DL, 1 ILB, and 5 DB's. 



The Rush:

The Nickel is edge pressuring off the slot while the rush OLB and DT work a twist game. Weak the DE is a B gap pop.

The Coverage:

3 under 3 deep firezone with the Nose spying the RB


Weak side the presence of a Rush OLB on the LOS, 4i DE, and shade Nose forces the C, G, T to set to the 3 threats. With the turn of the Center weak, the protection has 3 threats (Nickel, OLB, DT) vs. 2 OL and the scan RB strong. The twist creates confusion with the G squeezing to the most inside threat from the wrapping OLB. The OT fans to the Nickel instead of squeezing to the DT. The RB scans to the Nickel who is blocked by the OT leaving the DT on a free run. The protection has the numbers to account for the pressure but sorting it out is difficult. If sorted out the concept forces the RB to block across the formation on a full speed Nickel off the edge and the T/G to handle the twist 2 vs. 2.

The OLB walked on the LOS weak is able to key the QB's front shoulder intentions and buzz out to provide an underneath zone dropping body presence to the Corner. This prevents the Corner from having to be completely isolated in coverage and results in the interception.

The usage of the Nose as a spy on the RB is what makes this coverage execution work.

If the Ravens had truly rushed 5 and played firezone the weak seam dropping OLB is relating to the weak #2 (RB).

In this example the seam dropping Rush LB opens his drop to the #2 which leaves the Corner in isolation with the X. Why?


If the Rush were to key the QB's front shoulder intentions to the X and buzz out he could again help on quick game. However, if the QB resets his feet and throws the RB a screen or check down there is a hole in the middle of the coverage. The Seam and 3RH droppers strong are expanded to cover #2 and #3 strong. This is a specific risk as the Browns have two good RB's, screen is a threat from backed up field postion,and the Browns hit earlier in the game on both a TE screen and a RB screen. 


Notice the QB's front should intentions are initially away from the RB screen.

The decision to utilize the Nose as a spy helps solve this problem. The Seam dropping OLB can react to the front shoulder intentions of the QB and help undercut routes to the X. The Nose helps mitigate the risk on the RB screen and check down.

The usage of the Nose as a spy shows up in many defensive schemes.



This example is a completely different pressure pattern but illustrates another application of the concept. This example is from the Rex Ryan/Mike Pettine Jets. The current Baltimore scheme has crossover with the schemes of Rex/Rob Ryan.

The usage of the Nose as a spy not only helps the OLB provide relief to the Corner in coverage. It also:

1. Gives the Nose a coverage responsibility the Nose can execute and has a reasonable installation cost. Teaching a Nose a hook zone drop would be much more expensive to teach for example.

2. Helps manipulate the pass protection. The Center is occupied throughout the pressure mirroring the movements of the Nose. If the Nose drops off the LOS into coverage, the Center can potentially reset and provide help elsewhere in the protection specifically helping with the wrapping OLB from the pressure side. With the Center occupied with the spy Nose, the Center is a non-factor.

Really nice pressure design and usage of Nose spy from Baltimore Defensive Coordinator Wink Martindale.

Understanding the Opening Script

Many offensive coaches use an opening script to begin a game. What goes into that script? I had some ideas based on my experiences vs. opposing offenses, from film study of a variety of schemes, and from picking the brains of offensive coaches I've had the good fortune of working with in the past. I also reached out to a few offensive coaches to ask them for insight. Finally I crowdsourced info by asking coaches through twitter. The responses and willingness to share was amazing and a testament to the awesome "Football Twitter" community. The sheer number of responses was a bit overwhelming. To all those who contributed, Thank You!

After looking at the philosophy of offensive coaches as well as what they are scripting I broke the responses down into 5 categories: Identity, Diagnostic, Designer, Catalyst, and Cumulative Effect.

IdentityPlays that get scripted that are all about who the offense is at its core.

Top Plays - Call what the OC feels are the best run schemes and best pass concepts in the offense's arsenal. These calls are all about being who the offense feels they are as an offense and don't overly depend on the opponent's scheme.

Sure Things – Runs the OC feels can block any D look. This isn't necessarily the scheme the offense feels is their top production play or most explosive scheme. This extends to passes with protection that accounts the most possible looks. This might include max protection, play action, movement passes like boot/naked/sprint. Plays in this category are all about consistency and reliability. 

Get ball into the hands of the best player. What play calls guarantee the top player on offense is involved early?

Get multiple guys touches. A recurring theme was OC's wanting to get as many guys involved and engaged in the opening script as possible. This wasn't always just about getting the ball to the best player but getting everyone in on the action.

Get the QB in a rhythm. What plays allow for the QB to make easy throws? What plays have the easiest reads? This includes not only passes but also option schemes. How can the offense script to create consistent success for the QB early?

DiagnosticPlays that are scripted to diagnose some piece of info about the defense.

Alignment to formations – Does the defense align in the front and show coverage that match what was is to be expected from scouting report breakdown data?

Motion/trade/shift adjustments – How are they adjusting? Is there confusion or misalignments? Can offense move one player and get multiple defenders to move? Are adjustments being made by running defenders with motion, spinning/rolling coverage, bumping LB's, sliding DL? This can inform follow up play calls. 

Personnel – Is the defense using the personnel expected from scouting report info. Are players aligning where they were expected? Are matchups as expected?

How does the defense respond to something outside of normal? A new formation, formation into the sideline (FSL), unbalanced, empty, compressed formation, etc are all possible in a script to diagnose what the defense will do. This info can inform subsequent play calls or can be one offs.

Correction – Is there a formation, motion, or play the defense struggled with in previous games? Have they made corrections? Have they fixed what went wrong previously? Football is a copycat sport. This script element is all about forcing defenses to prove they have corrected their previous errors. 

Who made the play? – Typically this is about running a base/foundational play and looking at what occurred. Who made the tackle or made the play difficult? This informs follow up plays that compliment the foundational play. This could be series based play calling like many wing-t and option schemes utilize. This could also be just an if/then type of game plan. If the backside DE is chasing hard, then call the complimenting naked concept. 

Designer- Play specifically designed for the defense.             

OC are looking to script potential big plays or plays that create stress. This may be a shot pass play. This could be a trick play like a double pass, reverse, flea flicker, etc. This could be a scheme design from game plan meeting looking a the defense's previous plan. There is no perfect play call for the defense. Offenses know what stresses each defensive concept. It could be a personnel, motion, formation, or play concept but the OC is looking to craft those elements into stress plays in the script. Some designer concepts however are fragile. They may not be great outside of the specific/desired defensive look. Many designer looks in the script also carry a can/alert/kill concept. Two plays are called in the huddle. If the defense is in the desired look the designer play is on as planned. If the look is sub-optimal, the QB cans the play to a base call that holds up against more defensive looks. Some OC's prefer to do this with a check the sideline mechanic vs. asking the QB to can the play at the LOS.

Catalyst - Plays designed to provoke a response from the defense.

Catalyst concepts take many forms. Some may be simple like getting in a 3x1 and taking a shot to the X in isolation. The catalyst is all about looking to force the D to respond by playing some type of weak 2 over 1 coverage concept. The O certainly would like to complete the pass but the bigger goal was to create opportunities to the 3 receiver side or in the run game. Catalysts can be schemed in the run game also. The O may feel the best path to success running the ball is to get the DE aligned in a specific location on the TE. Scripted early calls like pin & pull may not be the O's most desired scheme. It is being scripted to encourage the defense to widen the DE's alignment, which sets up the opportunity to run other schemes on future plays. Not all catalyst plays provoke the same type of responses. Some OC's are scripting looks that are meant to confirm to the defense what the offense looks like. These are scripted calls that mirror the expected looks from the scouting report. The personnel, formation, play, etc was what the D expected based on film study. The goal here is to provoke the defense to be locked into their plan. If the D feels confident the O matches the scouting report, they are going to do what they planned to do on defense. Once the offense is locked into what the D's plan looks like it sets up the plan of attack. Most OC's don't like defensive variance so the catalyst may be to get the defense locked in a specific plan. Catalyst plays may take the form of setup plays. A distinct motion or formation leads the defense to talk it over on the sideline. When that look comes up again defenders make the ID and believe they know what is coming off that look. This may be where the setup leads to the payoff. The offense wanted the D to feel like they know what is coming and really cared much more about the payoff play vs. the setup play. Catalyst plays may be about manipulating defensive personnel usage. An offense that uses 11 but begins flexing to create 10 personnel formations vs. more traditional TE in the core 11 looks to get the D into sub-personnel. Once the D is subbing to Nickel or Dime, the O can attack those sub-personnels by putting the TE back into the core and running their base 11p package. The O may go 22 personnel to get the D in base personnel but create an empty formation and isolate a TE vs. a LB. Catalyst plays can take many forms but they want to force the defense into an action favorable to the offense. 

Cumulative effect - Plays that aren't about a single play but affecting the defense through repetition. 

Perimeter run/screen – The goal is to force the DL to run sideline to sideline. Tiring out DL early in the game can affect pass rush, run fits, block shed, pursuit and overall effort.

Establish tempo of the offense. Many OC's mentioned wanting to set or change the tempo in the script. This concept is also tied to creating fatigue on the defense early in the game. This may also get the D into more basic schemes. 

Attack the best player – If the defense has a great player the offense may look to make that player's life difficult. A defense with a dominate 3tech DT for example. The offense may script early concepts that double him, trap him, wham him, read him, and screen him. That player is now getting hit from all angles. The goal is to create frustration and prevent that player from getting going. A slow start for that player may keep him from getting going at all. 

Attack the worst player - Isolation of a weak link on defense with the goal that enough attacks on the weakest player will lead to big plays. It might not happen immediately but attacking as many times as possible is the best path to exposing the weak link as the weak link.

Being as multiple as possible. By showing various personnels, formations, trades, shifts, motions, and schemes plus varying tempo and snap count the defense has a lot to address and process. The goal is to slow down pressure looks including base pass rush and force the defense into basic concepts. Cumulative effect occurs from the the variety making the D be ready for anything/everything.

After doing this research, I have a different viewpoint of evaluating an offense's early play calling. It is always interesting to look at how offensive coaches think and plan. Hopefully there is something in this info that can help you and your defense or offense better understand the opening script. If there is something you think was missed be sure to reach out, I'd love to continue to build my understanding of the scripting process.

Speeding Up Slow Developing Plays

One reason to call pressure is pressure changes the tempo of a play. Slower developing plays like play action pass and screen will not work on the timing they expect to operate on if pressure forces the play to happen more quickly. 

A 2nd reason to pressure is plays designed to manipulate defender's reactions in base defensive techniques can find difficulty creating the desired effect vs. pressures. A pressuring defender isn't making the same run/pass read like in a base defensive technique. Attempting to fool a defender is harder when the defenders actions were defined pre-snap and are less reliant on a post-snap read/reaction. 

Here are four examples from Week 6 in the NFL

Buccaneers are in base personnel on 1&10 vs. 12 personnel.


The concept is a simple ILB edge pressure backstopped with 3 under 3 deep fire zone. The pressure forces the RB to adjust to make his block off his play fake to pick up a full speed edge rusher. The defenders aren't manipulated. The rushers don't buy the run fake. The pass droppers know the pressure can disrupt run or pass allowing coverage players to be coverage players who react to run not primary run fitters. The QB's play action tempo is too slow for the tempo of the pass rush created by the pressure. 

Giants are in Nickel personnel on 1&10 vs. 21 personnel. 


The Giants are bringing a 4 man sim pressure rushing the Nickel off the edge backstopped by a 4 under 3 deep coverage. The usage of  21 personnel, motion to a 2 back formation, and flash fake are designed to hold underneath defenders. If the underneath defenders are held there will be space to throw the switch verticals in the void created between underneath droppers and deep zone defenders. The rush changes the tempo and creates immediate pressure in the QB's face. The zone coverage specifically the roll down Safety is unaffected by the play fake preventing a void in coverage from being created.

Patriots are in Dime personnel on 2&9 vs. 12 personnel.


The pressure is 6 man blitz backstopped with Cover Zero man. The man coverage player on the RB engage rushes to add a 7th rusher when the offense presents a 6th blocker. The plus one pass rush requires the QB to account for the unblocked rusher. The QB has little to no time to react to an unblocked rusher following the quick play fake. 

Steelers are in Nickel personnel on 2&8 vs. 11 personnel.


The Steelers bring a simple Nickel edge pressure sending the DE wide and Nickel on a low track backstopped by 3 under 3 deep fire zone. The Browns are running a RB screen that is well schemed and set up for a potential big play with 3 OL leading the way for the RB. There isn't time for the QB to set up and deliver the ball off the play action fake. The DE who makes the play is in principle going to be controlled by a down block from the OT, orbit WR reverse bluff, and a TE blocking across the formation. The DE is edge rushing as part of the pressure preventing the down block/reverse manipulation and is too fast off the edge for the TE's block. 

Great stuff from Todd Bowles, Patrick Graham, Bill Belichick, and Keith Butler. Pressure is a tool and sometimes the tool is used to speed up slower developing plays and prevent defender manipulation.

4 Minute Defense

Last night in the Bears game the Buccaneers lead by a score of 19-17. Tampa took possession of the ball with the lead and 2:48 remaining in the 4th quarter. This put Chicago into 4 Minute Defense. The objective is simple, get the ball back to the offense with as much time remaining and in as good of field position as possible.

Every defense has rules, coaching points, and practice drill for 4 Minute Defense.

Here is an example from an old playbook of HOF Coach Dick Lebeau


Another example from former NY Giant Defensive Coordinator Bill Sheridan.




Most defensive playbooks have a situational football section with coaching for 2 Minute, 4 Minute, Final plays, etc.

The Bears did a tremendous job against the Buccaneers executing in 4 Minute defense. 

1st 10 from the -16 yard line 2:48 remaining. 


The Bears are in a reduction front vs. the Bucs 13 personnel. The front is spaced like a 6-1 with the walk down safety in a choke on the inside TE.


The gapped out alignment to the TE side creates a very difficult angle/block for the H. The 5 tech DE is able to create a TFL. Timeout Bears.

2nd 12 from the -14 yard line 2:43 remaining. 


The Bucs came back on 2nd down expecting Chicago to again go to a run heavy loaded box with man coverage. The Bears present a look similar to 1st down. Tampa calls a play action to attempt to attack the aggressive run stopping nature of the Bears' 4 Minute defensive call. 


The Bears use a 4 man rush Cover 3 on 2nd down instead. Chicago drops a LOS LB into the X's slant window and has zone coverage to handle the TE's and RB check down to the strong side. Incomplete pass stops the clock setting up 3rd & Long. 

3nd 12 from the -14 yard line 2:37 remaining. 


On 3rd down the Bears match the Bucs' 11 personnel with Dime personnel. The coverage allows Dime coverage on the RB as well as Safety help for the Corner on the X receiver weak. The TE stays in to help control a dominant pass rushing DE. Strong side the Nickel has help from the ILB underneath as well as Safety help over top in the slot. Incomplete pass and the clock stops.

Following the punt.


The Bears take over 2 yards shy of midfield with 2:21 on the clock and 2 timeouts remain. The Bears drove to kick a field goal to win 20-19.

Great execution from the Bears and Defensive Coordinator Chuck Pagano in 4 Minute Defense. This is a great example of why situational football is so critical. Defensively 4 Minute is area that must be coached and practiced in the same way 2 minute and other situations are handled in preparation.

It Really Isn't That Simple

This sack is a throw away play on 1st 20 late in the 4th quarter of the Memphis vs. South Florida game with the Tigers leading by a score of 49-10. From a game situation perspective it really doesn't hold much significance. 


The Rush:
End is contain working up the field with the 3 tech DT looping to contain opposite the pressure. The Nose is attacking the A gap before working to the interior pass rush lane opposite the pressure. The Mike is pressuring the inside half of the B gap and the SS is rushing the outside half of the B gap. 

The Coverage:
3 Under 3 Deep Firezone


The protection is a 6 man half slide concept.


The OL is sliding (Green) blocking the area to the defensive right. The OT is manned up opposite the slide and the RB is inserting/blocking edge threats inside out.

When the defense rushes two threats through the B gap the RB is overloaded 2 on 1 resulting in the unblocked fast pressure on the QB. 

The pressure pattern is a classic concept found in many defensive fire zone pressure schemes. The article could be summarized: Here's an a overload the RB fire zone pressure vs. half slide protection. Good design from former Memphis Defensive Coordinator Adam Fuller, excited to see his defense in 2020 at Florida State. That could be the end of the discussion.

I think there is more to this play than meets the eye on first look. Having more time available I've decided to write a more indepth article and take a deeper dive. Down the rabbit hole we go. 

The resource exchange for the offense is poor. The offense is blocking with 6 protectors while the defense rushes 5. The protection in theory should always be able to account for 5 rush threats. The defense may win some percentage of 1 on 1 matchups to create pressure against any protection. That is a reality of any pass rush situation. However that isn't what happened here. There is 6 vs. 5 and a rusher is left completely unblocked. How? Why?

Fire zone pressures are designed to create these problems. Zone dogs have been around for a long time creating these exact issues, they still work. There are numerous articles and examples on this site about fire zone pressure. What's the big deal? 

This article is less about scheme and more philosophical. There is a subset of coaches who love to toss around the acronym K.I.S.S. (Keep It Simple Stupid). The half slide protection is a simple idea. Simple concepts unfortunately don't always hold up under multivariable threats. 

If the defense would have brought the Will instead:



The protection is simple and clean vs. this look. The slide side knows they have help from adjacent OL and can pass the twist off. The diagram is clean and the outcome of the pass rush vs. protection battle comes down to the 1 on 1 matchups, coverage vs. routes, and the QB getting the ball out on time. 

If the Mike had been in a zeroed alignment and pressured the slide side, the protection again has a good answer.



The Guard can't allow the Nose to slant from the slide side to the man side and has to redirect his set and travel back. The Mike is isolated on the Center with a two-way go but again the pressure is accounted for by the protection. The pass rush vs. protection battle again comes down to the 1 on 1 matchups, coverage vs. routes, and the QB getting the ball out on time.  

If Memphis had run the exact pressure with the Mike aligned zeroed up:

The slide side OL could have seen the Mike pressuring to the B gap and the C/G could have redirected their sets to handle the pressure. The OL cannot let anything go from the slide side to the man side. Once again the pass rush vs. protection battle again comes down to the 1 on 1 matchups, coverage vs. routes, and the QB getting the ball out on time.  

When the Mike aligned in the B gap instead of zeroed up the protection has issues. The Mike is outside the vision of the slide.  A small change in alignment has a big effect. This is where complexity creeps in no matter how badly the goal is to keep it simple. Complexity comes in two types: obvious and hidden. To account for the Mike's alignment being in the B gap instead of zeroed up the offense has several choices some carry obvious complexity while others the complexity is more hidden:

1. Ignore the Mike's alignment and run the protection as called. The sack is an example of that concept playing out on film. While simple, the QB is pressured immediately. This likely occurred for South Florida because they were late in a lopsided score game with inexperienced players on the field. Those guys likely didn't make the necessary adjustments. No doubt the film session following the game included what adjustments should have been made.

But addressing specifically the keep it simple disciples out there - 

The KISS crowd loves to say:
"that way players can play fast" - players played fast on this play
"that way players can be physical" - it was a  physical play
"that way they don't have to think they can just play" - they did 
"they can play confident knowing their assignment" - no clear indecisive actions on the play

Simple doesn't solve everything. How can the players possibly pick this concept up without making an adjustment, without adding complexity? It doesn't take many plays like this sack for players to get frustrated. Doubt quickly creeps in and players thoughts become "this protection doesn't work". 

2. Ignore the Mike's alignment and run the protection but the QB has to throw hot off of 2 extra rushers to the man side.  


The RB handles the 1 extra rusher and the QB must account or the 2nd. This is problematic because the defense can force the offense into throwing hot off of 5 man pressure or potentially a 4 man sim/creeper pressure. This significantly hinders intermediate and deep passing game concepts. The ball will routinely need to be thrown fast and short. It also requires the route concept to always have a built in hot route or WR's to use sight adjustments to account for the pressure. The QB also has to have all of his read progressions start on that side of the formation. The QB cannot see the hot if he isn't looking that direction. In the clip the QB's eyes are opposite the pressure. He never sees it coming. The ball has to be thrown accurately under duress from an unblocked rusher, the WR has to make the catch and get YAC to make it truly be effective. There is a great deal of complexity to undertake for the offensive coaches, QB, and WRs to select this option all to keep the protection simple for the OL/RB. Additionally this just isn't how hot routes work. Most offenses will not build a hot concept unless the pressure cannot be accounted for numerically by the protection. Hot routes most often come into play on 6+ rush looks with no deep safeties. This goes back to resource allocation. When the O has 6 blockers vs. a 5 man rush it should not make the protection have to throw hot, ever. At least that is likely the goal for the offense.

3. Change the slide and flip the RB. Either the OL or the QB has to change the slide direction. 

The offense has to ID the issue based on the Mike's alignment and communicate the new slide and the RB has to change alignment. The RB is opposite the slide to account for a potential 3rd rusher from the man side. If the RB is working to the man side, the QB is still hot to the slide side. The protection cannot handle the 4th rusher to the slide side. This has all the same hot throw problems as option 2. 

The protection can ask the RB to use a scan technique in this situation.




Now the RB will check his side then scan across to the opposite side. The protection has the pressure picked up in concept. Now we are getting somewhere. Unfortunately for the offense picked up doesn't equal protected. The block for the RB on a full speed rusher across the formation is a very difficult task. It may seem simple to change the slide and flip the RB. But there are a bunch of issues. This has to be repped in practice repeatedly to be used in a game.  The offense has to know how to do it, when to do it, how to communicate it, and how to get that all done on a play clock plus all the technique required to actually execute the protection. The RB needs significant reps of flipping alignment and making a scan block. The protection has to coached to ID the Mike's alignment and communicate/understand what is happening and why. The QB, OL, and RB have to be on the same page. The QB also has to get comfortable with a scan running back flashing in front of him and they both have to learn to co-exist when the QB looks to step up in the pocket or step into a throw to drive the ball down the field. Also flipping the RB has to be programmed into other plays in the offense. If the only time an O flips the back is to adjust the protection for drop back pass the defense will scout that up in film study. A defense may not check into a pressure on RB flip but simply knowing if a play is a run or pass pre-snap is a huge advantage. None of the complexity means this isn't a viable option. This option can get the QB protected and create a clean pocket. 

4. Change the slide leave the RB's alignment.



Back to the problem of having 4 to the slide and needing the QB to throw hot.

If the RB scans all the same challenges exist as in option 3 in terms of coaching and practice time.





The pressure is blocked in principle and the execution may be easier on the RB. The RB checks the Will. With no pressure the RB can stay on his side to pick up the SS. The challenge for the RB in this protection is what happens if the Will is rushing. Any block where the RB has to cross all the way across the formation is a challenge. As with all calls you gain something and you give something up. This call may improve the situation for this pressure but make other pressure pickups more difficult. Again a viable option to create a clean pocket.

5. Bonus the protection



Bonus says the offense is going to put the slide and RB on the same side. This creates a 4/2 protection principle with 4 blockers to one side of the Center the protection can block the pressure. This requires the QB, OL, and RB to ID the situation communicate and get this adjustment made pre-snap and executed post-snap. The RB's block is significantly easier. Another viable option for the offense to protect the QB.

It also isn't without risks. The protection is weaker opposite the slide. Two man twist games to the man side will get no help.



This is a good example of the isolation that occurs when the T/G are manned up vs. a twist with no help. This protection example is likely big on big man protection concept but conceptually the struggle is the same for a bonus protection. 

Bonus protection may force a player to travel back with no help.



The same pressure earlier in the game with the RB working to the slide on a bonus. The Center oversets and the Nose is able to win across his face. Adjustments can help account for the pressure they don't solve 1 on 1 matchups.

Bonus protection also has to scan the RB to Will pressure which is a difficult pick up.



Bonus protection can work and like all calls has strengths and stress areas.

6. OL adjust to a man protection principle when the Mike shows



In half slide protection the first uncovered OL starts the slide. In the initial picture that is the uncovered left guard from the defensive perspective. As the cadence starts the Mike shows early. The guard could make a 5-0 call telling the OL there are 5 treats at the LOS. Now all the OL are covered and all need to use man protection principles. Several things have to happen for this to be viable. The Guard/QB has to make the ID and communicate. The QB needs to control the cadence potentially even giving a "Easy, Easy" type of call to allow the protection to communicate and sort out what needs to happen before restarting the cadence. The Center is now in man and has to set to the Nose and travel back when the Nose crosses face. The Guard and Tackle are also manned up and have no slide help on inside movement to their side. It takes significant work to make a quick protection adjustment during the cadence happen. Again a viable solution but does up the complexity.

7. Call man protection instead of half slide from the start



Man protection or Big on Big (BOB) has the OL handle the 4 down DL and a declared Mike in the this case the OL would say " Mike 3 Mike 3". The blocks are just like option number 6. The big advantage is the OL doesn't have to make an adjustment during the cadence. This isn't without challenges.

In a half slide the OL can't depend on help from adjacent OL. In man protection OL end up going 1 on 1. The RB also has the challenge of going coast to coast. The RB setting to the SS has a difficult scan to the Will. If the RB sets to the Will he has a tough scan to the SS. And a Saw concept is a problem for the protection.


Memphis like every 4 down team has a version of SAW attacking both edges with pressure.

8. Check to Full Slide Protection


The offense still needs to make the ID and communicate. The RB could flip or not. This solution takes a great deal of stress off the RB. The RB on this pressure doesn't have a DE to block. However, in other pass rush situations the RB may have to block the defense's best rusher off the edge. The slide has challenges too. The Guard has to bypass the immediate threat in the B gap from the Mike and push his set out to the SS in the widest part of the B gap. The Center has to bypass the Nose and set wide to the fast threat from the Mike. The back side Guard has to hit a set that stops the Nose from immediate pressure on the midline while also avoid being too aggressive and oversetting the Nose.

Full slide away from the pressure forces the RB to be overloaded. The OT has a B threat from the Mike, the result is two off the edge vs. the RB. The RB vs. the DE is likely and advantage for the D. The overload give the RB no good option.

9. Get the RB out into a route or screen and put the pressure on the defense.

The idea is straight forward. Instead of adjusting the protection, get the RB out and stress the pressure by stretching the defense horizontally and vertically. In a similar line of thinking check/alert the play to a screen. Either way the offense is thinking the stress on the defense will punish the defense for bringing pressure.


Same pressure vs. a RB swing double screen concept. This is a play getting the RB out and a screen on the same play. The edge widens with the RB on the swing and the pressure forces the QB to throw it away. The dropping DE is a problem for the WR half of the double screen. This doesn't solve the fundamental protection problem. How do you protect a drop back pass when you want to throw a drop back pass? 

There are more solutions for the offense but there isn't a need to keep going the point is hopefully made. The reality is pass protection has rules and defenses can manipulate them. A simple Mike alignment change creates big challenges. Offensive line coaches and pass protectors have a very difficult task. On both sides of the ball it is easy to fall into the keep it simple mindset. Who will own the blame when the simple concept breaks down? For me it cannot fall on the players. If the concept needs to be adjusted to work, it needs to be adjusted. We have to accept complexity is necessary and embrace it. Teaching why the complexity exists and how it allows us to be successful has to happen. When a simple concept is broken by moving the Mike a few feet, complexity becomes necessary.
