Basically, your DL is not giving up inside lanes. They're attacking and forcing the natural gaps inside closed, either with their body or squeezing the OL down. This forces everything to bounce outside, where your outside backer is containing. Look at a power out of the way he has the defense drawn up. Backside guard pulls, play-side (TE side) is down blocking .Well, that 3 technique is attacking that guard's "outside V of the neck", or his outside shoulder. He will be double teamed, so he fights across the tackle's face so the tackle can't "chip" and get to the linebackers. Center is down on the nose, who is also fighting across the center's face. Your backside inside backer is reading that pulling guard, so he's heading "midline", or towards the center's position, and he's hitting a cutback lane. All the while, he's reading through the line. If he sees the ball carrier moving to the outside, he stays flat down the line until he sees a definite gap that the ball carrier will hit. Strong side inside backer gets the double team read on that 3 tech, so he's heading towards c/d gaps. Depending where that defensive end goes (should be going tight and meeting that pulling guard, forcing the play to bounce and not hit B/C gap as it is designed), he is attacking that TE and keeping outside arm free. Again, squeezing the TE down so the gap is only north/south. Outside backer is seeing that TE release on inside backer, so he knows he needs to get tight and a couple yards into the backfield so he can force the play upfield or to bend towards the sideline. If It goes sideline, the boundary is the 12th man and you have your pursuit angle. If he cuts back it's a tackle, and the angle forces him out of bounds for minimal/no gain). Corner is filling. Safety is filling. This defense is perfect for middle and high school football. Ran it in high school and we perfected it. We lined up slightly different, but the concept is the same here.
great breakdown coach!
Similar to the umbrella concept? Spill players within the tackle box and force players are positions such as the overhang safeties/OLBs and corners
Thank you
Not the biggest of fan of the CB's assignment, prefer him to have secondary contain, other than that, great explanation of the 4-4 defense.
what do you mean by bounce?
