I don't see much discipline on this defense. Coaches should be held accountable for mindless penalties, confusion, and lack of confidence. Also, there has to be at least one guy out there on defense that knows what's going on. The coach on the field player. The go-to guy that players can rally around. I don't think it has as much to do with size, depth, or technique as people think. If a D1 player doesn't already know how to play, he shouldn't be out there to begin with. Coaching is about motivating players more than teaching them how to play. It really is that simple.
