Saban does what every successful CEO has done for eternity. He surrounds himself with the best. Saban runs that team like it is his own NFL franchise. He is the coach, GM and owner. He does what every successful Nascar team does, he finds and uses the grey areas of the rule book to his advantage. He does one thing particularly well, he is not afraid to change his system. He loves winning toooo much. Why do you think he hires all these fired coaches to be "analyst." He uses them for their knowledge.
Do they cheat? Probably. Until it is proven, it is all hearsay. You will never be able to prove he was behind anything. It will be put on some analyst as a fall guy. Good luck trying to find dirt on him.
