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.

Disguising Sim Pressure

Here is a really nice example of a well planned pressure disguise and execution from the Cleveland Browns. 


The Rush:

End working a super stick to cross the Center, the Nose attacks/engages the Center before looping to contain. The Dime is up the field to contain with the Nickel going through the Dime's heel line on a straight line run to the QB.

The Coverage:

4 under 3 Deep Cover 3


The disguise from Cleveland is very impressive because of the multiple layers of disguise elements and the attention to detail.


The first element is following the motion the Dime walks out of the box and presents an alignment and demeanor of a coverage player. His tempo, stance, and body language all help sell him as being in coverage. 

The next element is the presentation of 4 rushers from the left. This affects the set of the RG. The RG sets to 4 rush threats to allow the OL to have 4 blockers for the 4 rush threats. This also forces the OT to be manned up on the DE to the strong side. 

The third element is the deep Safeties subtly showing a weak rotation. The subtle disguise helps sell the 4 from a side weak overload. The offense is looking for clues to help define where the pressure is coming from. A 4 from a side weak pressure presentation with strong rotation safeties can tip the OL the 4 weak will be dropping out. The Browns really sell the 4 weak pressure at all three levels of the defense. 

The OT being manned up forces the OT to set inside with the DE on the inside movement. The RB is left with a 2 on 1 overload vs. the edge rushers. The pattern with the Dime up the field forces the RB to block the first threat. The Nickel is actually the inside most/direct line rusher which should make him the most dangerous. The RB cannot afford to block the first threat that shows in order to sort out the pressure pattern. Once the RB commits to the Dime the Nickel is left on a clean run to the QB. 

This is another example of why defenses are using sim/creeper pressure concepts. Very rarely does a traditional 4 man pass rush result in an overload on the RB and a free run to the QB. Sim pressures can manufacture pass rush opportunities with 4 rushers that typically require bringing 5 or 6. 

Great pressure design and even better coaching of the details from Cleveland Defensive Coordinator Joe Woods.

3 Buzz Weak Flood Coverage

The Chargers are in Nickel personnel on 3rd&10 vs. 11 personnel.

The Chiefs are in a 3x1 with the TE in a reduced split.

The pre-snap coverage look is 3 buzz weak playing a 4 under 3 deep zone coverage.

Kansas City has a plan to attack the expected coverage on 3rd&10. 


The route starts with the reduced split Y on a width release curl/stop route past the sticks. The route is designed to widen the Corner in his 1/3 as well as pull the curl-flat Will LB out wide.

The inside WR to the strong side is running a spot curl setting up on the opposite hash in the weak hook zone. The Slot is going over the top of the spot route on a deep over route. The goal is to create a high/low on the buzz safety in the weak hook. If the Safety jumps down on the spot route at the sticks the over route has a void to attack. If the buzz safety stays deep for the over the spot route can sit down at the sticks for a 1st down completion. 

Strong side the RB swinging is designed to hold/widen the Hook/C-F defenders. The outside WR is running a basic. If the Hook dropper squeezes back inside with the crossing routes the basic can be a 3rd option after the high low on the weak hook.

The Chargers however are not running just a zone 3 buzz weak. They are flooding the coverage. The Chiefs have the RB strong representing a 4 strong load pattern distribution.

The coverage is man from the back side Corner. With the Corner handling the Y 1on1, the defense can distribute differently. With the Corner no longer playing a deep zone he no longer needs a C-F dropper to handle the routes in the underneath zone. The weak side curl-flat dropper can drop to the #4 instead of zone dropping the C-F. The defense now has an underneath dropper working to 1-2-3-4.

When the RB (#4) runs a route strong the Will LB opens to the strong side looking for the first crosser. The Will is in great body position to handle the crosser coming back across on the spot route. When #4 goes strong the buzz Safety can pass the 1st crosser to the Will. The buzz Safety is free to handle the new #3 coming across (S) on the over route. By matching the buzz Safety on the over route, the void area the offense was attempting to attack is no longer available. Having the Will/Buzz Safety distributing this way eliminates the high/low in the weak hook zone. Strong side the Mike is able to get into the window of the new #2 (Z) on the basic while the C-F Nickel leverages the RB in the flat. 


The Mike ends up squeezing inside with the QB's front shoulder intentions. With the spot and over routes covered the QB takes the Y on the 1on1 vs. the Corner in man. The QB is pressured by a great 4 man pass rush which helps force an errant throw. The pressure also prevents the QB from having time to work back to the basic route. 

Cover 3 is a simple concept. Teams that run Cover 3 variants as the bulk of their coverage concepts have all the nuanced adjustments to handle whatever offenses throw at them.

Well done from the Chargers and Defensive Coordinator Gus Bradley.

Cover 3 Safety Sim Pressure

 The Ravens are in a specialized pass rush Dime Personnel on 3rd & 5.



The Rush:
The DE's are contain with the Nose working away from the pressure. The Safety is pressuring the weak side inside pass rush line.

The Coverage:
Sting - 3 Under 3 deep Firezone with a free/bonus dropper to create 4 under 3 deep concept.

With the mugged up A/B gap threats and the safety bluffing pressure strong the OL slides to the strong side rush threats. The slide allows for the pressure safety running through on the RB 1on1. The coverage creates confusion also. The initial look is 1 high pressure, but when the post aligned safety rotates down the look simulates a zero pressure. The QB has to ID one safety rotating down while the other is popping the top to the post. 1 high coverage that rotate to 1 high can be difficult to quickly ID under pressure. 

In coverage the free/bonus dropper is able to collision the #3 receiver which helps make the 3RH droppers job easier. The seam droppers hang in the seams as opposed to expanding to the flats.

Nice pressure design from Wink Martindale.

Cover 3 Sim Pressure vs Empty

The Ravens are in Nickel personnel with OLB bodies at DE vs. 12 personnel empty on 2nd & Long.



The Rush:

The front is spaced like an even front in over G. The Mike walks up running a twist game with the DT. The 2i DT is looping to contain opposite the pressure.

The Coverage:

Sting Concept - Sting is a 3 under 3 deep firezone with a 4th dropper as the free/bonus dropper. The end result is a 4 under 3 deep 3 buzz like coverage.

Here is another example of Sting vs. Empty from the Rex Ryan/Mike Pettine. 




The OL is in a 5 man protection. The usage of the DT in a G helps influence the Center. The Center is looking to give the guard help with an inside shaded DL. When the Mike walks up the defense has 3 rushers overloading 2 blockers. The Center is forced to redirect to a full speed inside LB. The T/G do a nice job squeezing inside to take the most inside threats. The G loses his 1on1 but the T/G do a nice job of taking the 2 most inside threats and leaving the widest rusher. The QB drifts away from the unblocked rusher to give the protection a chance. 


Without knowing the call the coverage is difficult to tell. I think it is Sting because of other sim pressure concepts the Ravens have run as well as the coaching tree Wink Martindale comes from. However, this could also be 3 buzz with 2 Curl-Flat and 2 hook droppers.




Why differentiate between sting and 3 buzz? Playing a sting concept allows the defense to maintain it's firezone coverage principles when bringing 4 instead of 5. The Ravens bring 5 and play fire zone regularly. A concept like sting can help eliminate complexity. It can be easier on players to stay this is fire zone with a free/bonus dropper when rushing 4 instead of a different coverage like 3 Buzz. The 5th rusher is simply replaced by the free/bonus dropper in Sting to create the 4 under 3 deep coverage.

Nice job creating pressure with a non-traditional 4 man pass rush from the Ravens and Wink Martindale.

Nub TE Trips Stress Route for Cover 3 Coverage

The '17 Raiders are in 12 personnel trips with a nub TE weak following the motion.


The concept is a 4 strong load route distribution. The coverage in the example is a 4 under 3 deep zone drop cover 3. There are two C-F droppers and two Hook droppers.

With the Will LB dropping to the weak C-F drop the Corner should be able to get depth to deny the Y on the cross to the weak side. The issue is the release of the U. The Corner is threatened by the initial width vertical release. The Corner cannot allow the U to attack vertically and outside in his 1/3. By gaining width to keep leverage on the route the Corner is taken further from the Y's route. 


The stress falls on the weak hook dropping ILB to handle the Y running across. Many spot drop zone cover 3 concepts don't ask the hook dropper to carry 3. The expectation is the Corner will be deep in the 1/3 waiting for the route to arrive from the strong side and the Post Safety will be in the MOF, the Hook dropper's help carrying vertical routes isn't needed. The U's release/route make the Corner's ability to cover the route in his 1/3 more difficult.

For the teams that want to play a flood cover 3 concept using man principles on the weak side to allow the coverage to flood the strong side there are still issues.




For some flood concept teams they would have the Will handle 4/1st crosser. With 4 (RB) releasing strong the LB can look up the crosser and roll back with the Y.


For other flood teams using the Mike as a 3 up is 3 player, they won't push him off his roll back with the Y. In this case the Will works strong with 4's release and replaces the Mike.

In either case the coverage is better vs. the Y's route. There isn't the same expectation of the Corner being deep in the zone requiring a low player to roll back with the route. 

The issue for flood coverage is still the U's route. The Corner is isolated on the U. It is easy to say the Corner has to be able to man cover a TE. Where the challenge is created is the space. The Corner is again attempting to leverage the U into a huge amount of vertical and horizontal space. The Corner has to position to deny the vertical and outside breaks off the initial release of the U because there is no coverage help in those areas. The Corner's position works against him when the U works back in to all the open space created inside by the low defenders flooding the coverage strong. The Corner is the better athlete but is forced into a disadvantaged position. 

The route is nice concept to stress common Cover 3 variants and a good design from the Raiders. This is route to work on in pre-season when coaching up stress routes vs. Cover 3 family coverages.

Cover 3 Sim Pressure

The Ravens are in a Dime personnel on 2nd & 10.


The Rush:
Both DT's are slanting to balance the pass rush with the ILB pressuring the B gap and the Rush LB as contain.

The Coverage:
Sting - Sting is a 3 under 3 deep fire zone coverage concept with a bonus free dropper

The protection is a 5 man scat protection with the RB free releasing into a route. The presentation from the Ravens controls the turn of the Center. The OL are looking for the 5 most dangerous rushers. The 5 up look makes the OL account for the 5 defenders on the LOS first and foremost. The Guard to the pressure side is forced to block the 3 tech on the inside movement with C-G-T setting opposite the pressure.  There is no guarantee the Center will be able to provide any help. Once the weak side DT works out the Center ends up freed up. Even with the Center able to help, the Center and Guard would have a difficult time redirecting to pick up the DT and ILB on the pressure once they set to the initial threats. The Center would need to redirect to the DT on the inside move from the pressure side and bump the Guard out to the B gap ILB. That is a difficult and unlikely redirection and pick up scenario. The OT has the Rush LB on the edge when the ILB pressures the B gap adding a second threat creating a 2 on 1. The OT makes a threat assessment and blocks the more dangerous of the two. The inside rusher is the bigger threat with the fastest path to the QB. The OT sets the ILB leaving the edge rusher unblocked. This is the value of a sim pressure. There are very few times a traditional 4 man rush results in the OL being forced to cut a DE/OLB edge rusher free on a run at the QB. Simulated/creeper pressures create this type of stress on pass protection. 

The coverage appears to be a Sting concept that shows up in the Ryan coaching tree.  Baltimore Defensive Coordinator Wink Martindale has coaching crossover with Rex at the University of Cincinnati and with Rob with the Raiders from '04-'08 . Without knowing the call it is difficult to be absolutely sure the coverage is Sting but this clip creates an opportunity to discuss the coverage. Here is an example from the Rex Ryan/Mike Pettine Jets. 


This example is a completely different personnel package and front structure but the coverage is the Sting concept. The coverage is using the firezone distribution with a bonus free player. This is different from a 4 under 3 deep cover 3 with 2 hook droppers and 2 curl-flat droppers. The 3 under are playing seam-3RH-seam  fire zone coverage but adding the bonus dropper as a free player. The free player's role can be game planned up to fit the opponent. In the clip the free player collisions the #3 before zoning off. This concept is very disruptive to 2/3 route combinations in a 3x1 formation. The collision of the free play also buys time for the 3RH to work from the opposite B gap mug alignment to the #3's route. For the protection manipulation to work the 3RH hook player alignment and drop put him in conflict. The free player's technique helps mitigate some of that conflict. 

Nice sim pressure design from Wink Martindale.

Odd Front Sim Run Pressure

The 2014 are in a odd front spaced 3-4 personnel.


The Rush:
DE's are in a 2 gap technique, Nose slants away from the A gap pressure ILB 

The Coverage:
Quarters



The non-pressure ILB deepens and zeros up allow him to play C gap to C gap. The pressure in front of him cancels the gaps and provides protection. The A gap pressure dents the back side of the play helping disrupt the 2nd puller in the counter scheme. The 2 gap DE is able to throw over the top of the B gap cutoff block of the OT allowing him to get involved in the play front side. The non-pressure ILB is unaccounted for by the blocking scheme with the 2nd puller unable to roll the hole.

A 2nd example of the same concept. This time the coverage is a flooded cover 3 vs. a 3x1. 




The pressure gets a play side run through allowing the LB to chase the play. On the edge the scheme cannot account for the roll down Safety. The TE blocks the force playing Nickel. The roll down Safety is in the alley inside force, unblocked at the point of attack. 

Nice sim pressure concepts from former Eagles Defensive Coordinator Billy Davis.

Defending Sail Route in Cover 3

The 2017 Titans are in 3-4 personnel playing a 4 man rush Cover 3.


The Browns are in a 12 personnel bunch running a naked off zone blocking with a 3 level sail route to the the strong side.




The sail route is designed to put the strong C-F player in a high low bind. The Corner is gone with the 7 route. The C-F defender is shown a hard run action. This helps control the depth of his drop. Next the C-F defender is being quickly out leveraged to the flat. If the C-F defender stays low on flat route the crossing route will be open behind him and under the deep 1/3 Corner. Sail route is a stress route on cover 3 for this reason.

The Titans use some nice techniques to mitigate the stress area in Cover 3.



The strong side C-F defender uses a sail technique. Initially he runs to the flat route. As he regains leverage on the route he opens his hips inside and gains depth. This gives him the vision to the see the QB and work into the throw window to the crosser. The post safety uses a nail down technique. The Safety comes out of the post and takes over the crossing route. The Corner replaces the Safety in the post. The nail down not only helps cover the crosser it also helps flatten his route. If the crosser attempted to climb to gain more depth over the C-F defender the nail down Safety can undercut the route. The crossing route's depth helps the sail technique C-F defender make the play.



Great stuff from the master Dick Lebeau in is final NFL season.

Manipulating Pass Protection Match-Up with 6 Up Alignment

The double A gap mug look is a common alignment used at multiple levels of football.



This type of alignment forces the pass protection into 6 games of 1 on 1 with the RB in the protection. Often the protection requires the RB to account for a A gap rusher. The A gap threats in this look are LB's. Assigning the RB to a LB who has a higher probability of dropping into coverage compared to a DL can keep the RB from needing to make a pass block some percentage of the time. The offense could also possibly give the RB an End, however a pass rushing DE is typically a worse match up for the RB than a LB.

The 2014 Eagles come out in a Dime Personnel with OLB bodies as the DE's on 3rd & 12. The expected spacing is something like:


The Eagles could have built the 6 up look from there by walking the Mike & Dime up in the A gaps to build the double A gap mug spacing.


Instead the Eagles use the Rush OLB's as the A gap threats and walk the Mike & Dime up as the edge pass rush threats.

The Rush:
DTs both expand through B to contain. The Rush LBs are both through the A gaps.

The Coverage:
Cover 3


The pressure and coverage concept are simple staples. A four man rush using four traditional rush threats and backstopped with a basic cover 3. The usage of the Rush LB's in the A gaps affects the protection in a significant way.


The protection is a 6 man half slide concept. The OT & OG are manned on the Dime & DT leaving the Rush 1 on 1 vs. the RB. This is a mismatch especially because the Rush was Connor Barwin who had 14.5 sacks in '14. The pass pro does not want the RB 1 on 1 with an elite pass rusher especially not straight down the middle in an A gap. However, the protection has rules for handling a double A gap mug and those rules put the RB on an A gap threat. Pass protection is like the Matrix.



The Rush LBs in the A gaps stresses the protection's double A gap mug rules. It is easy to sit back and say "well if this player is the A gap threat protect it this way, but if the Dime is on the edge block it like this...." but that is all way easier said than done. Changing up pass rusher alignment is a simple effective way to attack protection by creating mismatches. 

The Eagles alignment also allows the more athletic Mike & Dime to be the zone pass droppers and keeps the DTs and Rush LBs as pass rushers. 

The coverage has to deny the quickest easiest throws to allow the four man pass rush to get home.



The coverage is rotated down to the strong side with the Corner over the X receiver playing an off alignment. The Safety weak works to the post. If those indicators tell the QB to look and work weak to the X in isolation vs. the Corner the quick isolation throw isn't there. The Dime running out to the Curl-Flat drop allows the defense to effectively double cover the X eliminating the iso to the X as an option. The strong side route combinations don't have time to develop with the quick A gap pressure from the pass rush getting the QB off his launch point. 

Nice pressure design to create mismatches from former Eagles Defensive Coordinator Billy Davis.

Ambushing Power Read

Wisconsin is in a 3-4 personnel using the field OLB as the 4th rusher. The spacing created is like a 4-3 over front.


The Rush:
4 man rush with the Sam as the 4th rusher in the charge.

The Coverage:
4 under 3 deep Cover 3 concept

Nebraska is in 12 personnel with both TE's flexed as receivers. The RB is aligned as a receiver before the jet motion to run jet power read. The concept could be a stress play for this defensive call.




If the Sam runs up the field to the jet sweep, the read will be a clear keep for the QB. The run will hit behind the pulling Guard/Double team off tackle. The Will LB will have a difficult fit and task to make the play. The Mike has to block shed vs. a flexed TE.


If the Sam sits at the LOS or crashes flat down the line, again there is a clear read for the QB. The ball will get handed to the jet sweep. The offense has a 3 for 3 on the perimeter including a TE on the Mike and a Corner who will be slower triggering from the deep 1/3. 

Either outcome is a difficult run fit for the defense. The Badgers instead chose to ambush the power read.


The Sam attacks up the field off the edge. The read key is up the field the ball should be kept on the power. Once the Sam is up the field he flattens off to play the QB. Simple plan: force the keep and tackle it. The QB's action meshing with the jet keeps him deep in the backfield giving the Sam the chance to play up then go flat.


Good technique and pressure design from Jim Leonard to take the stress out of a stressful play with edge rusher technique.

Spread Defense Sim Pressure Package

This is a guest post from Nick Davis the Defensive Coordinator/LB Coach at Rose-Hulman Institute of Technology. If you don't know Nick, you should look him up. He is one of the brightest young defensive coaches in the country. Follow him on twitter @Spread_Defense. Nick regularly posts video and drill work on social media as well as having several great articles on X&O Labs. His defensive units are annually tops in the Heartland Conference and highly ranked in all of D3 football. Nick has been able to fill up the stat columns in Sacks and TFL's every season with a dynamic multiple defense based out of 3-3-5 personnel. Nick's defense was 9th in the nation this season with 38 sacks. 

Simulated Pressure 

A simulated pressure in our terminology is a pressure that brings linebackers or defensive backs while replacing the rusher or rushers with defensive lineman.  At Rose-Hulman this has become really easy to get to in our system because of our personnel.  We are a 3-3 personnel team that will play both odd and even fronts.  Our fronts allow us to put our linebackers or best cover defensive lineman where we need them.  Our base defense allows us to rush 4 from multiple fronts and play 1 & 3 match coverages.  

The most important part about a Simulated Pressure is trying to figure out the pass protection.  We look for over a 60% tendency when we game plan.  When you have figured out what the protection is going to be then it is time to figure out what type of fronts you want to attack them with.            

3 Down Odd Front
We want to put the most athletic defensive end to the running back side.  If we have over a 60% tendency we will bring both the middle and outside stack backer to the man side of the protection with any blitz pattern.  If you are not sure what the man side of the protection is you can send both stack backers with any blitz pattern.  We like this best with our 1 low hole coverage.  We train the defensive end that if the tailback runs a swing to his side he will peel off on it and owns that in man. If the tailback swings opposite he becomes the low hole player and drops to 5 yards and works off the quarterback.  The linebacker not rushing is the low hole player unless the tailback swings opposite the defensive end.  If the tailback blocks you get a five man rush with a low hole player.




2 & 4 Down Even Fronts  
We want to put the most athletic linebacker or defensive end to the running back side.  If we have over a 60% tendency we will bring the linebacker to the man side of the protection with any blitz pattern.  If you are not sure what the man side of the protection is you can send both backers and let your c gap players play the tailback and the low hole.  The coverage concept is the same as if we were in the odd front but now we have a better match up on the tailback if he free releases.  We prefer to bring the linebacker down the A gap but you can use any of your blitz patterns.




Why do we love sim pressures?

We can get hits on the quarterback only bringing 3 or 4 rushers.  We can bring 5 or 6 man pressure patterns and still have 7 or 8 in coverage.  We prefer to use this with our man coverage but we can play our whole coverage package behind these pressures.  These concepts teach our defensive line coaches coverage and thus they become more involved in our overall defensive system.  The defensive lineman think it is fun to play in coverage and get excited about the concepts.
