Man Under 2 Deep Corner Pressure

Here is a a creative pressure dialed up by Pittsburgh defensive coordinator Keith Butler.



The Steelers are in a Nickel personnel with two stand up Rush OLB's playing the roll of  DE's. The initial alignment is press corners and a 1 high safety concept.

Rush:
DT - Loop to field side contain
Will- Walked up in the C gap, working B gap to A gap to the opposite inside pass rush lane
Rush - Contain
Corner - Inside rush lane

Coverage:
Man under 2 deep with a safety replacing for the blitzing corner. The Nose is playing man coverage on the RB. 

The coverage is man under 2 deep which allows the man coverage players to play aggressive technique knowing they have help over the top. The disguise prevents the offense and the QB from identifying the coverage is man under 2 deep. The difficulty of coverage recognition forces the QB to hold on to the ball. 



The Nose, Rush, and walked up Will occupy the Center, Guard, and OT to the weak side. The Center doesn't realize until it is too late that the Nose is actually in coverage and not a pass rush threat. With the Center occupied the Guard is forced to block the Will and the OT is locked on the Rush. The Corner has a clean pass rush and is able to attack the RB deep in the backfield. If the RB didn't scan across the formation, the Corner has a clean run to the QB. As it plays out, the weakest link in protection (RB) is forced to make the most difficult block and loses the 1 on 1 to the Corner. 

Creative combination of disguising 2 man coverage with a non-traditional 4 man pass rush from the Steelers.

Man Under 2 Deep Pressure

Here is an interesting pressure concept from the Cincinnati Bengals last season. 



The Bengals are in a 3-2-6 Dime personnel.

The Rush:
The DE backs off the LOS pre-snap to a LB depth & alignment.
Mike & End crossfire in the A gaps. Mike is 1st - End is 2nd
DT's - Working B gap to Contain

The Coverage:
Will - Man on the RB
SS - Man on #3 strong
Dime - Man on #1 weak
Corner & Nickel man on #1 & #2 strong
FS and Corner - Deep 1/2



The coverage looks like a 1 high coverage pre-snap but becomes a 2 deep coverage post-snap. A 4 man pass rush that looks and feels like a 6 man pressure helps speed up the read and throw for the QB. Tight aggressive man under 2 deep coverage makes the windows to throw into very small. Coverage disguise + perceived pressure + tight coverage = effective 3rd & 9 call.

4 Man Full Line Twist

Here is another example of a twist that was a focus of a previous post about Don Brown's defensive scheme. This example is from the Falcon divisional playoff game vs. the Seahawks.


For the specifics of the twist, check out the previous article. The coverage was backed up by a cover 1 concept from a dime personnel.






Good stuff from Dan Quinn.

Bear Front Middle Overload Blitz

Cleveland Browns' Defensive Coordinator Ray Horton brought this middle overload blitz in week 17.

The Rush:
Will - Contain
Tackles - B gap Pressure
Nose - Midline
Mike & Safety - A Gap

The Coverage:
The coverage could be a cover 1 variation or a 2 under 3 deep match up zone concept. Without knowing the call it is hard to tell. Either way the coverage defenders are playing very aggressively on the receivers knowing the overload pressure is going to prevent the QB from holding the ball. 



The protection has the numbers (6 vs. 6) to pick up the rush. The conflict for the OL is expected threats vs. actual rushers.


Initially the OL has an easy pick up in concept. The OL handle the 5 rush threats on the LOS and the RB has the Mike backer if he rushes. 

When the SS rolls down into the box to rush the A gap and the Sam drops in coverage, the clean 6 vs. 6 picture changes for the OL. The OG and OT who set to the initial threats of the DT and Sam would be forced to redirect to the inside to pick up the new rushers.



The OT could see the Sam drop and redirected inside. The Guard was already engaged with the DT and missed the redirection leaving the SS unblocked in the A gap.



Even if the Guard identified the Sam dropped into coverage, the blitz pick up is difficult. The Guard has to redirect to block a full speed blitzing SS. The OT is left alone on a 3 technique with an inside rush lane to the QB. Both blocks are difficult.
The OT has a tough situation when the SS rolls into the box as well. The OT could set to provide better body position on the 3 tech. By setting this way the OG and OT would have a better chance to redirect to the pressure. The issue is the OT doesn't know the SS is going to rush or that the Sam is going to drop. The walked up LB on the LOS is the more likely rush threat than a high safety rolling down. If the OT doesn't set the Sam, the risk of getting beat on a speed rush goes up. The percentages say the Sam is going to rush therefore giving the more likely rusher an easy speed rush is an unlikely plan for the OT. 

Why didn't the QB throw hot? The protection can pick up 6 in principle but cannot block 7. Five rushers on the LOS plus the Mike & SS is 7 in the pressure picture. Once the Sam drops from the LOS the pressure picture no longer has 7 threats. The read to throw hot is not clear. There is a QB adage "If you don't know, don't throw." and in this situation the QB has a confusing picture to process. 

The coverage is also designed to denying hot throws. The corners are pressed and denying anything easy to the outside. A MOF safety is over top of the inside receivers. The 2 underneath defenders are there to play any quick throws to #2 or #3. 

Unclear hot read + tight aggressive coverage + immediate unblocked A gap pressure in the face = sack. Good stuff from the Browns on 3rd & 6.

Quarters Coverage Zone Pressure

Here is an interesting zone pressure run by the NY Giants this season. Giants' Defensive Coordinator Steve Spagnuolo dialed up a non-traditional 4 man rush from a Dime personnel group and backed up the pressure with quarters coverage.




The Rush:
Nickel & Dime - Contain Rush
Mike & Nose - A gap, Inside rush lanes

The Coverage:
3 under 4 deep zone coverage

Corners & Safeties - Quarters
DE's - Attack the OT, Drop
Will - Show pressure, Drop


The bluff of the pressure by the Will LB attracts the attention of the RG which prevents the guard from being able to help with the rushing Dime. The attack and drop tech of the DE results in the OT blocking no one. 

Another factor in the success of the pressure is the usage of the Nickel and Dime as outside rushers. This pressure could easily be run from a traditional 3-4 personnel with OLB's filling the role of the contain rush. The OL reacts differently to OLB's as rush threats than they do to Nickel/Dime DB players. An OLB is a 50/50 or higher percentage chance of rushing the QB. A DB is much less likely to rush and the OL are less inclined to pass set to a DB aligned at or near the LOS.  

Good stuff from the Giants defense. This is a creative way to generate pressure while rushing 4 and playing quarters coverage on 3rd & 9.

Atlanta Falcons' Nickel Zone Dog

Here is a zone dog rushing the nickel the Atlanta Falcons have busted out several times this season.

The Rush:
Nickel - Contain Rush
DT - Penetrate B gap
DE - Loop to A gap
DT - Inside Rush Lane
DE - Contain Rush

The Coverage:
3 Under 3 Deep Zone

The bluff of pressure by the Mike and Will linebackers helps control the pass protection of the Center and the RB.  



Here the bluffing Mike forces the set of the Center away from the pressure. The bluffing Will attracts the block of the RB. The result is a 3 on 2 leaving the Nickel unblocked.



Here the offense motions to empty. The Center sets away from the pressure to the initial threat of the bluffing LB's. Again the result is a 3 on 2 with an unblocked nickel.


Here the looping DE beats the redirecting guard. The DE pressures the QB into sliding off his launch point in the pocket.  The Nickel is accounted for by the TE. The looping DE affects the QB buying time for the Nickel to beat the TE 1 on 1. 

The pressure has yielded good results for Dan Quinn and the Falcons.

Dallas Cowboy Zone Dog

Here is an interesting 5 man dog from the Dallas Cowboys' Defensive Coordinator Rod Marinelli. 

The play starts in a standard 4-3 2 high safety shell look.


During the cadence the DL stems the Nose and DE into this look.



The Nose moved to a head up zero technique and the DE went from a wide alignment to head up on the OT.

The defense then stemmed a 2nd time into this look.



The Nose moved to a strong side 1 technique and the Sam backer walked up on to the LOS. The stemming by the defense allows the Cowboys to create a odd front structure and bring a 50 front type of pressure.



The Rush:
Sam & End - Contain Rush
End - Inside Rush
T&N - Delayed twist

The Coverage:
3 under 3 deep



The penetration of the Nose in the A gap forces the Center's shoulders to turn. The delay twist by the Tackle is able to loop tight and pressure the midline.

Using pre-snap stemming and DL alignments are creative ways to incorporate Odd front concepts into a base Even front defense.
