First, let's get this out of the way. This is NOT a thread about getting rid of a coach. I hope most of you are not like that idiot who called for firing DL coaches (think about that one). I hope Mattison stays as long as possible and enjoys good health. So, if you want to spew about who should be replaced with who, go elsewhere, there are plenty of threads about that.
What I want to talk about is why Mattison is so averse to pressuring bad QB's.
Is it because of the time he spent in NFL where there are many quarterbacks who will carve up the blitzes? Rushing four is definitely the main tools of the best D's in NFL (Seattle, Baltimore, etc.). But is it really necessary in college?
College QB's are not like NFL QB's. Even very good college QB's do not handle pressure well (see Devin), let alone poor ones like Hackenberg (still a freshman) and Cook. But it seems like we are determined to give them as much time as possible and let them be comfortable in the pocket with ever increasing percentage of completions as the game goes on and they gain confidence.
I just don't get it. You can see how much havoc pressure can cause (see MSU). We are very effective when we blitz (I have numbers). I understand rushing only four is preferred, but why keep doing it when it is not working?
