If I was Dabo, I would just use the BAMA vacancy (when it happens) as leverage for more money for him and his staff. Unless there's some craziness at CU behind the scenes, and you never know - there might be, I think he'd be crazy to leave Clemson. Better quality of life (SC>AL) and the expectations will be Saban-esque, where as at Clemson he is already permanently cemented as the goat.
Again, you never know what's truly going on behind the scenes at any time, but all things being equal, I would stay put if I were Dabo.
