IMO, the head coach is only part of the equation. The coordinators are just as important. That's probably a statemetn of the obvious but i've not seen it discussed much here. Mack at Texas has seen his fortunes rise and fall with our defensive coordinators. Same goes for PC at USC. With Chow he was lighting it up. Hasn’t been quite the same since. The next coach needs to be able to find and hire the best coordinators he can get.
