JJ, that's correct. Philly was running a wide 9 with those DEs.
Similar to what Miami did under Jimmy Johnson, I believe.
As spill players, our defensive linemen are looking to attack the inside shoulder of any blockers or ball carriers attacking to their gap. This will force the ball to "spill" to the outside. On the outside, we use our Safeties (quarters coverage) or Corners (cover 2) to contain the play. We teach our Defensive linemen to spill plays using 6 steps:
Get Off: Fire off the ball low and hard on the snap, stepping to the crotch of the defender you are shaded on.
Engage: Shoot your near hand to the V of his neck. The outside hand will control his shoulder pad.
Escape: On our third step, the linemen are looking to escape from the Defender. They will RIP off with their inside arm to gain control of their gap and work to the football. We are not simply taking up space! Our defensive linemen are athletes too, and we want them to be playmakers!
Bend: Versus any down blocks, our defensive linemen are bending down the line of scrimmage immediately. We tell our linemen to treat any action away from them as "Run Away" and begin to chase. If the play is coming back, you will collision a pulling blocker!
Wrong Arm: In engaging a pulling lineman or other blocker, we will use our outside shoulder to attack the inside shoulder of the lineman. We are aggressive in engaging the blocker, attacking with the outside 4/5 of our body on the inside 4/5 of his body. We want to blow up that blocker. By wrong arming the trapper, we are forcing the play to bounce to the outside.
Chase: When the play has begun to spill to the outside, we get into a pursuit angle down the line. We want to be in position that, once the runner is forced back inside by the contain player (usually the Safety or Corner), we can make the tackle.
So basically occupy blockers and let your tacklers (Zach Thomas, Ray Lewis) make tackles. I've heard that with DT's in 4-3's, never realized it for DE's.
Thank you both.
