4-2-5 Basics: Run Fits vs. 2 Back Formations

People often ask me about how we fit the run in the 4-2-5. They say things like:

"4-2-5 is just a 4-4 with DB's at OLB, so you just fit the run like a 4-4?" or
"4-2-5 is just a 4-3 using nickle sub personnel on every play, so you fit like the 4-3?"

My answer is "Yes" to both. Part of the reason the 4-2-5 is popular is that it can fit the run like a 4-4 or like 4-3. Teams can tailor the fits to their needs. Take for example a basic two back 21 personnel pro formation.

The defense can align and fit the run like a 4-4. The SS and WS play force while the four down linemen and two inside linebackers account for all the interior gaps. 


The defense can choose to fit the run like a 4-3 with a safety filling the roll of the third linebacker.

In this example the defense bumps the linebackers (Mike & Will) strong and bumps the WS into the box in the roll of the third linebacker. Against a strong or weak flow running play the Mike, Will, and WS fit the run like a Sam, Mike, and Will in a traditional 4-3 defense would fit.

Versus a strong flow run

Versus a weak flow run

The defense can alternatively choose to bump the SS into the box and the linebackers weak. The SS, Mike, and Will then fill the roll of the three linebackers.

Versus a strong flow run

Versus a weak flow run

Lastly, the defense can drop the FS down into the box to fill the third linebacker roll.

Versus a strong flow run

Versus a weak flow run

How can a defense use this multiplicity? 

Take for example:

Here is a standard Iso or Lead play from a 21 personnel Pro I formation. If the defense chooses to fit this play like a traditional 4-4 defense, it can become a stress play.

In this scenario the Mike LB fit the FB on the outside half. If the inside linebackers are expected to bracket the fullback, the Will has a difficult job. The Will needs to align wide enough to keep leverage on the guard in case the offense is running an outside flow run weak, like outside zone. This prevents the Will from cheating his alignment too far inside. The result is the Center and Guard can scoop the Nose up the Will, potentially cutting the Will off from his bracket responsibility. 

One alternative solution is to have the Mike spill the fullback.

The Will LB's job is easier because he doesn't have to bracket the FB with the Mike. The new challenge is if the Mike is fitting inside of the fullback's block, who is fitting outside? The offense has a good angle to use the TE to block the SS from folding into the box. That leaves the FS. The FS can make the tackle but not without issues. The RB vs. FS may be a bad match up.  The FS may have to make an open field tackle vs. a full speed RB. Requiring the FS to be hyper aggressive to fit the run also opens up play action risks.

Neither fitting the Mike inside nor outside of the fullback may be optimal for the defense.

Some coaches may say:
"The DT needs to squeeze the guard's block and reduce the A gap."
"The Nose needs to control the scoop block, keeping the offensive lineman on the line of scrimmage longer. That buys time for the Will."
"The Mike needs to be violent and jam the fullback back in the hole."
"The Will needs to read his key and be quick to attack the ISO."

These are all true. The issue is that may be easier said then done. Especially when playing good teams. If you want to compete for conference and post-season titles you are going to have to play and beat good teams. What is the solution when their fullback is better than your Mike? What if the guard is getting movement on the DT consistently? Being able to change how the defense fits the run can help give the defense solutions to these problems.

Here the defense bumped the linebackers strong and is using the WS as the third LB.

With the Will bumped over the Center the Mike and Will have much easier time bracketing the fullback's block. The offense does not have an easy angle to block the Mike or Will.

More examples:

When the offense is using an offset fullback or an unbalanced set, the defense can sure up run fits by bumping to a 4-3 run fit.

Having the linebackers bumped can help get players to the point of attack. The offense most likely wants to run toward the offset fullback. It makes sense to get extra defenders where the offense wants to run the ball.

Here is an unbalanced formation. The offense most likely wants to run toward the unbalanced side. Being able to bump to a 4-3 run fit can help the defense remain gap sound even against the extra gaps created by the unbalanced formation. TCU coach Gary Patterson wrote about the concept of bumping in the 4-2-5 in his article for Nike Coach of the Year. On pages 6,7,8 of the article Coach Patterson explains TCU's slide and scoot concepts. 

There are other times when the defense wants to fit like a 4-4.

Here the defense is in a 4-3 run fit. If the offense is running a read power to the weak side the defense may have difficulty. The WS has a poor angle to force the wide path of the lead blocker. If the End steps down with the down block of the OT, the Will LB ends up in a 1 on 1 foot race with the RB. This may be a bad match up. 

If the defense is fitting the run like a 4-4, the angles are much easier for the defense. The WS has a natural force leverage from width on the lead blocker. The Will LB can much more easily scrape over the top of the DE and pursue the RB. 

The 4-2-5 has the added advantage of disguise. On any play the LB's could bump during the cadence. Any of the three safeties could move into the roll of the third linebacker. The defense can also show a 4-3 fit and bump back into a 4-4 run fit. The result is offenses being force to constantly identify, communicate, and react to a defense changing it's run fits.

The versatility and flexibility are major contributing factors in the success and popularity of the 4-2-5. I'm going to continue the Basics of the 4-2-5 series this off-season as I have time. If there is anything you would like to see, drop a comment or send me an e-mail.

Diguising Blitzes in the 3-3 Stack

The season is rolling along and the tried and true blitzes that were installed in pre-season camp have by now been called multiple times. Every opponent has several films and has developed a scouting report on a defense's most common pressures. How can a defense get continued production from the same blitzes it has been running all season? One solution is using tags words to disguise blitzes and create confusion for the offense's blocking schemes. Tag words allow the defense to continue running the blitzes it executes well, while creating new looks and challenges for the offense.

Here is a sample blitz from the 3-3 Stack. The blitz is an America's Blitz concept with 3 under 3 deep fire zone coverage behind it.

The blitz is SMACK - Sam & Mike, End to A Gap. The goal of the blitz name to tell the rushers where they need to go.

The Rush:
Blitz DE: Long Stick to A Gap
Nose: Away A
Away DE: Contain
Sam: Contain Blitz
Mike: Scrape Blitz the B Gap


Bluff tells the non-blitzing LB (here the Will) to show a blitz in the B gap. The call would be Bluff Smack.


Con tells the non-blitzing LB (again the Will) to show a Contain Blitz . The call would be Con Smack.


Fool tells the linebackers to show 2 blitzers opposite the called blitz. The Mike and Will in this example are the Fool linebackers. The Mike bails out during the cadence and executes the Smack blitz. The Will drops into coverage from the L.O.S. The call would be Fool Smack


In tells the DE's to align inside (here in 4i's). In also tells up the stack LB's (Mike & Will) to walk up to the L.O.S. The DL and LB's run Smack from the IN alignment. The call would be In Smack.


Big tells the LB's to bump their alignments to the blitz. Big can help improve the blitzer's angles. Big can also cause blocking scheme headaches for the offense. If they are preparing for a defense to stay stacked and now the defense is bumping to a non-stacked alignment, can they handle it? The call would be Big Smack.

Another blitz in the package is SMOKE - Sam & Mike blitz (Sam is 1st/Mike is 2nd), DE is Outside

Smoke can be tagged using the same naming system. Here is Bluff Smoke.

Here is Fool Smoke.

Smoke can also be tagged with Alpha, Bravo, or Charlie. The tags tell the 1st blitzer where to show a blitz. 

Alpha - Show A gap blitz
Bravo - Show B gap blitz
Charlie - Show Contain blitz

Here is Alpha Smoke. The 1st blitzer (here the Sam) shows in the A gap. The Sam and Mike execute a Smoke.

Here is Bravo Smoke. The Sam is aligned showing blitz in the B gap.

Finally, here is Charlie Smoke. The Sam shows a contain blitz then executes a Smoke.

Another blitz in the package is MONSTER - Mike & Sam blitz (Mike 1st/Sam 2nd), End Outside

Monster can be tagged just like Smack and Smoke. The differences happen on Alpha, Bravo, or Charlie. The Mike is the 1st blitzer and shows on Monster. For example an Alpha Monster call tells the Mike to show in the A gap then execute the Monster.

Having a system of tags for your blitz package can create greater versatility without installing new blitzes. Versatility can come in handy as the season goes along and opposing offense's know more about a defense. Tags also come in handy in the post-season when a defense may have to play a team for a 2nd time.

First Game of the Season

The season is almost here. A thought for defenses:

"It is the first game and you are nervous. It is ok to be nervous. Nerves mean you care. You are nervous because you want to do well. You are nervous because you want all your hard work to pay off. You are nervous because you don’t want to let your teammates down. Those are all noble reasons to be nervous. When human beings are in stressful situations one of two instincts takes over: fight or flight. Tonight when the nerves and stress build up: will you fight or will you run? If you are a guy who wants to fight, great. Buckle up and go out hit ‘em every play. If you feel like running, that’s ok too. Run to the ball. When you get there you will know what to do."

Good luck to everyone. Enjoy every minute of the 2015 season. May your team stay healthy, may your defense shed, pursue, and tackle, and may the sacks be plentiful. Amen.

Evaluating Red Zone Productivity

Interesting article by Barry Hoover about evaluating offensive efficiency in the red zone.

This type of statistical tool is good for self-scouting your offense or evaluating your defense against opposing teams. Coach Hoover is also the author of the Coach Hoover website.

Attacking Quarters Coverage with a Zone Run/Post RPO

This concept is a Run Pass Option (RPO) play that combines outside zone blocking with a post route. 

Here the concept is being run from 11 personnel and is attacking the weak side of a 4-2-5 quarters coverage defense. The OL and Y are blocking outside zone (stretch) with even numbers (6 vs 6).
The Defense has the advantage of being +1 as soon as the WS reads the TE is blocking and gets into a run fit. This concept is designed to read the weak safety. The QB will shuffle while meshing with the RB. The QB's vision is on the WS. 

If the QB reads the WS coming downhill into the run game, the QB will pull back and throw the skinny post. The post is leaning his outside shoulder on the corner before breaking the route deep and skinny. The goal is for the WR to win the 1 on 1 against the corner who has no post help. 

If the QB reads the WS not committing downhill to defend the run, the ball is handed off on the outside zone. 

This type of run pass option is safe way to take a shot. The play has a chance to be a homerun post or an efficient run.
