Petrino without a doubt and twice on Sunday. For one, Petrino has won big at 2 different schools. When a coach wins at two different school, like Saben, Spurrier, Bill Self, Miles, Meyer, and Roy Williams, it almost always signifies that they are just not the beneficiary of certain situation, but rather a very very good coach. Furthermore, Petrino is potentially the best offensive mind in college football, while At best, Chizik is a decent college football CEO coach that needs top flight assistants in order to be successful. I am sure there are more reason, but those are just a few off the top of my head.
