I don't really get the disdain for him. I've heard from several people "anyone buy Dykes" (not on this board) and I'd just ask why.
I guess he hasn't won enough championships, he's not young enough, or charismatic enough....whatever it is. All he's done is produce pretty good football teams, and at some places where that isn't easy to do. If he somehow stays at SMU, they are set up to be good again next year, if not very good. And I think maybe more than any of the other candidates being considered he wants to be at TCU, and would probably consider it his destination job.
