If Kelly really was after putting in the spread, he would not have recruited the OL guys he did. The guys he picked up this year are monsters, road graders, Alabama-esque.
I think this guy has figured out a few things. It starts with D and it ends with being able to run the ball. That is the formula, and with his past success at developing explosive offenses, I think he is creating something that can be both. Explosive, score in seconds and capable of wearing you down by pounding you with a stable of backs and big ole road grader behemoths.
