If you are going to dig into the college ranks...I want a guy that beat the Goliath with David. I don't want the guy who is Goliath. I don't want the guy with a roster full of 5 star recruits..because how can you tell if that guy can coach...as opposed to just overwhelming everyone with a deeper roster.
I will never forget Steve Spurrier....when he got hired to coach Washington...making jokes about NFL coaches sleeping on the couch in the office. He just KNEW that would not be him. He thought he could just "roll the ball" out..and overwhelm people like he did in college. If you evaluated John Calapari based on what he did in the NBA....you would argue the guy can't coach...but put him at Kentucky...and give him the best recruiting class every year....and he looks unbeatable
I have often said Garrett is better suited for college...because he would rather out execute you...than outcoach you. He needs a roster that is full of players better than the players on the opposite sideline. Far too often that does not happen in the NFL. Everyone is big fast and strong. So you need a gameplan, scheme, and intestinal fortitude on gameday to give your team and edge. So no, I would not want Saban.
