Saban no, he tried and failed the NFL and went running back to college.
I don't know if Sumlin can handle the NFL and if his system would work.
Also you have to bring in a offensive coach because I don't see Jerry firing Kiffin after one year.
Brian Kelly is the only college coach I would want.
Lovie Smith would be a interesting coach because he would keep Marinelli and Kiffin and would need to bring in a OC.
I would also like to have Greg Roman or Jay Gruden both also offensive guys that would keep the defensive staff.
also Roman would most likely bring Geep Chryst as OC.
