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.
