Arkansas, Ole Miss, and Miss State are screwed as long as Saban is at Bama. Bama and LSU will sumo wrestle for top billing, and Auburn/A&M are the 2nd tier, in terms of program quality. You can either cheat (like Ole Miss) to matter for a couple of years (no West titles, though) or hang onto a top-tier HC as long as you can before he moves on (Mullen @ MSU), otherwise you have no shot. None.
Arkansas hasn't (as far as we know) cheated and they haven't gotten an elite HC on his way up, so they've been irrelevant. It's unfortunate, but true.
