I think both of them are way down their list (way, way down). I think Jimbo Fisher is near the top & could be the selection when it's all over. Others on the list might include:
Jimbo Fisher
Art Briles
James Franklin
Gus Malzahn
Jim Harbaugh (they don't have a chance in Hades of getting him, but I bet he's on their list)
David Shaw
I have college coaches on this list since the Texas AD says he wants someone with a college background, but I doubt he would turn down a major NFL coach. Petrino could be a possibility if they get really desperate.
