I hear the CEO of Crumble Cookie, an alum, is doing whatever it takes to keep the BYU coach there. Again, he has built a culture there, and recruits a specific type of player. BYU is formidable. It would be an interesting move for him.
As for Rhule, I like him better than Pelini or Frost. Callahan just never fit. Although, it seems the last two years he's gotten a bit more chippy about Iowa. He seemed broken and at a loss post game. He did admit Iowa was the better team.
Much like Fickle, you almost have to ride it out with him and hope for improvement. But next year their schedule is considerably tougher and I think recruiting is tanking by the day. I think his stock with Penn State has tanked too. Earlier he made have had some bargaining ability, but I think even Penn State questions his ability to lead that program.
I would bet if he stays next year will be a make a break year for him. Otherwise the bug eaters will run him.
