Unless we're really young, we know what good D line play looks like. Jason Peter said something to the effect that they were taught: the defensive tackles play run first, rush second and the defensive ends play rush first, run second. All in the context of a pressure defense. Stop the run and force the QB to make quicker than he'd like decisions. The reasons to stop the run first are obvious and a QB under pressure is likely to make mistakes and it helps the defensive backs cover and get picks. That was the formula. And it produced legendary defenses for Nebraska. Under this philosophy we didn't win all of our games all of the time but we had great confidence that who ever we played was going to be in for a long afternoon. We've gotten away from this philosophy. I don't know if its a stop the pass first approach but it seems like it. I do know this though, there have been far too many losses and far too many unnecessarily close games, in large part, because of it.
