I have no Idea who could take over in the middle of the season. One of our existing coaches would probably take over on an interim basis, but that isn't going to win us many games either.
Following the season I'd love to try and get Bud Foster from VT, but that isn't going to happen. My 2nd choice would be Will Muschamp from Auburn - especially if Tubs gets canned or Charlie Strong from Floridawho may be tired of sharing the DC job with Mattison.
On the short list would be Mike Hankwitz of Wisconsin and Jon Tenuta of Georgia Tech. - Brent Venebles would be great if they bring back Mike Stoops once he's fired and Venebles leaves OU.
