I have been saying for weeks now that the Big 12's main problem is that they won't get their head out of the ND/Arky/BYU clouds. And when that's where you're looking, everything else is a disappointment. Even FSU and Clemson. *Especially* the likes of Louisville. It's one of the main reasons I have been less than worried about the probability of Louisville leaving. They still want Notre Dame.
With the TV money the BE is probably looking at, absent more bloodletting, I find it vanishingly unlikely that Boise and SDSU back out. At this point, I think it's less unlikely that the MWC loses AFA than that they get those two back.
