Simple Under Front Cover 1 with 4-2-5 Personnel

Here is one easy way to play the the under front concept with 4-2-5 personnel. The coverage concepts are a continuation from the Cover 1 terminology and rules used in other articles.

The call is Track 1. Track tells the SS to track (align to) the TE and cover him man to man. If the TE is attached, the SS will align in a 9 technique. The Front is set with the 3 technique away from the TE. The corners and remaining safeties will cover the skill and handle the post. The ILB's have a fiddle (2 on 1) vs. the RB. One backer will end up in man on the RB while the other will be the Rat.

If the TE is into the boundary the SS will track the TE and align into the boundary.

Against a single width formation the Corners are over.

Against TE trade the SS will again track the TE. The DT's will adjust.

If the offense elects to go Y off and align the TE off the ball, the SS will back off the ball as well.

The SS still aligns to the TE side. Now the ILB's and SS will use funnel technique to play 3 vs 2 man coverage vs the RB and TE. 

If the offense flexes the TE, the SS will adjust out and cover the flexed TE. 

We also have a pressure built off this concept. Strike 

Strike is SS track and rush. The coverage now has an ILB on the TE with the other ILB on the RB. 

In Strike against a Y off formation the ILB's will use a Banjo (2 vs. 2) man coverage technique on the TE and RB. The SS always aligns to the TE. 

Track 1 and Strike are an easy way to play Under front cover 1 and pressure to the TE. The rules are simple and the concept can be installed quickly if you are already playing other Cover 1 coverage concepts. 

4 Man Pass Rush Twist

Here is a variation of a read twist vs. the pass. The DT's are running a read on the center. This is a concept we have called Torch in the past. If you want a full explanation of the Torch stunt click this link. Here is the short version description of Torch. DT's both slant to the Center. Center to you - wrap, Center away - penetrate. 

Here the Center is away to the Nose penetrates. The Center is blocking to the Tackle so the tackle wraps.

When the Center blocks to the Nose, the Nose wraps. The Tackle penetrates with the Center blocking away.

We also have a stunt for the DE's called Eyes. On an Eyes call the DE's read the guard to their side. 

If the Guard is blocking out to the DE, the DE stays in the outside rush lane.

 If the Guard is blocking away from the DE, the DE CAN use an inside pass rush move. The DE is still looking to beat the OT in the fastest pass rush possible. This give the DE a two way go on the OT. 

If the protection is full slide the End will crash hard off the edge, the DE can rush underneath the block of the RB.

When we combine Torch and Eyes we call Take.

TAKE

Left DE - Eyes with Guard Away = Inside pass rush move
Nose - Center away = penetrate
Tackle - Center to = wrap 
Right DE - Eyes with Guard to = Outside Rush

If the slide side was to the defensive left.

Left DE - Eyes with Guard TO = Outside Rush
Nose - Center to = wrap
Tackle - Center away = penetrate
Right DE - Eyes with Guard away = Inside pass rush move

Vs. Full slide protection

Left DE - Eyes with Guard away & OT down = Under the RB, Inside rush lane
Nose - Center away = penetrate
Tackle - Center to = wrap
Right DE - Eyes with Guard to = Outside rush

If the DE got a great takeoff and has the OT beat with speed, the DE may choose to stay outside on the Eyes stunt. As the DT wraps in this case the stunt turns back into a Torch.

Take is an easy way to build on a great stunt like Torch, turning a 2 man read twist into a 3 man pass rush game.

Attacking the Slide Side with 3-3 Stack

Stack spacing allows for all kinds of interesting and effective pressure concepts. One classic 3-3 pressure is to bring the stack backer and Mike to the same side of the center pressuring the inside gaps.

This pressure has been around for a long time. Unfortunately the pressure is easy to pick up in a half slide pass protection. The Center and Guard are in good position to see and block the Sam and Mike. The Will can green dog the RB and generate pressure that way. Ultimately this concept comes down to personnel and who in the pass rush can beat a blocker. One way to improve this pressure's effectiveness is to add a read concept. As opposed to the previous 3-3 read concept that attacked the RB's alignment, this concept attacks the slide side of a half slide protection.

The concept is similar but the read elements to the rush create opportunities for the Nose, Mike, and Sam. The pressure is set away from the back. If the back was aligned to the Sam, the Sam would green dog and the Mike and Will would be in the pressure.

The Rush:

Ends - Contain

Nose - Work opposite the pressure, read the Guard

Mike - Fast pressure in the A gap, Read the Guard

Sam - Read the Guard, Pressure B gap to Midline

The Coverage:

Cover 1 with the non-pressure LB using a green dog technique on the RB. This could also be a 3 under 3 deep fire zone coverage.

The Reads:

Nose - If the guard blocks to you, cross face to the inside rush lane

Mike - Guard away, wide in the A gap and stack the guard. Inside rush lane. 

The Mike and Nose both widen in this situation to create the midline rush lane for the Sam.

Sam - Attack the wide B gap. If the Guard sets to, wrap to the midline rush lane.

The goal here is to create a twist action with the Mike and Sam. If the Mike penetrates the A gap and stacks the guard, the center is forced to set deep and commit to blocking him. When the Sam wraps to the midline the center has difficulty passing off the Mike and picking up the Sam.

If the offense decides to slide the protection to the alignment of the RB the pressure still works.

Nose - Guard away, widen and stack him, inside rush lane

Mike - Guard to, redirect and stack the Center, midline rush lane

Sam - Guard away, run through the B gap, be ready for the block of the RB

This also works if the offense is flipping the alignment of the RB late in the cadence. Read pressures can help defenders to win in the pass rush by creating win/win pass rush opportunities.

Adding Pressure to Split Field Coverage Trips Check

Most 4-2-5 coaches are familiar with the concept of split field coverage. Get your DB's to call the coverage on the field and put your defense in the the best coverage available vs. the formation the offense presents. The formation is split in half and the safeties call the coverage for their half of the formation. One popular quarters coverage trips adjustment has the safety away from trips work strong side to help with #3 in the 3x1.

Some call this concept Poach (Saban/Belichick/Smart) or Solo (Patterson). The name is really not important. The concept is simple, vs. a 3x1 formation the the coverage adjusts with the backside safety. To the 3x1 the Corner, FS, and SS play a quarters concept just as they would vs. only 2 receivers. The LB to the 3x1 drops to #3 handling all low routes. The WS works to #3 and handles all vertical routes. The Corner and LB to the single WR side match the X receiver and RB in coverage. 

One simple adjustment to get more pressure in passing situations is to exchange the roles of the weak side DE and Mike LB. 

The Mike and Nose are reading the turn of the protection by keying the Center's block. The DT plays B gap and pops to contain. 

If the Center blocks to the Nose, the Nose widens and handles the inside rush lane. The Mike stays on his A gap rush and should expect the RB's block. This situation keeps the RB from free or check releasing to get into a route.

If the Center blocks to the Mike, the Nose keeps penetrating and takes the opposite inside rush lane. The Mike attacks the A gap and reads out when the Center blocks toward him. The Mike wraps around the penetrating Nose to the opposite inside rush lane creating a twist action. If the Center is blocking toward the Mike, the guard is forced to chase the penetrating Nose. The Mike's wrap timing is critical. If the Mike goes too early, the Center/Guard can see the twist. If the Mike's timing is correct, the Nose has stacked the Center and the Guard is committed to the Nose allowing the Mike to wrap and create pressure. 

With a simple tag word we can have a pressure trips check in our split field coverage concept. 

Read Pressure from the 3-3 Stack

The 3-3 stack spacing has many options for both blitzing and bluffing pressure. One of my favorites vs. 10 personnel is a read pressure. The rush reads the turn of the protection and adjusts to give the rushers the best possible rush opportunity. The pressure is based on the RB's alignment. 

Rush:
DE's - Contain
Nose - Slant to the RB (Reading Guard)
Stack LB opposite the RB - Rush A gap (Reading Center)
Stack LB to the RB - Rush B gap (Reading Guard) read out to Wrap

Coverage: 
3 under 3 deep firezone or Cover 1

If the back was aligned on the other side the roles would adjust. 

The Reads:

Sam - If the Guard blocks down Run through in the B gap. Expect the block of the RB. Inside rush lane.
Nose - Guard blocks toward you, redirect to the midline, Stack the Center
Will - Center to you, widen to inside rush lane. Stack the Guard

This is a situation where you can really turn up the heat by going Cover 1 instead of Cover 3 fire zone.

In a Cover 1 situation the Mike can use a green dog technique to overload the the RB. Both the Cover 1 and Firezone versions have applications.

When the turn of the protection is toward the RB the pressure adjusts.

Sam - Guard to you, wrap to opposite inside rush lane. We want the Sam to initially attack the guard then wrap. Wrapping too early disrupts the timing with the Nose and Will. 
Nose - Guard away, widen to inside rush lane, stack the guard
Will - Center away, midline rush

This pressure could also be set away from the RB. By doing this the defense will likely get the 3 man twist action to attack the slide.

Allowing rushers the opportunity to read and adjust the rush can help  in a number of ways.

#1 Helps players understand how pass protection schemes work
#2 Helps players understand they have a role in the defensive scheme but that role can change post snap based on the offense's scheme
#3 Increases confidence the call can work in any situation
#4 Helps players develop the "be a playmaker" mentality. We want our guys to understand they are not simply "running calls" they are making decisions that either help themselves or hurt themselves in terms of playmaking and production. We are constantly working to coach the mindset  of "I'm blocked" out of players. The opportunity to produce within the scheme is there on every play.
