I believe Carroll knows the NCAA is about to drop the hammer...they just hit the basketball program for the OJ Mayo stuff and I think he wants to bail before it hits in typical slimy Carroll fashion
The NCAA may drop the hammer on USC. But not only do I doubt they would, I doubt it even less as long as Carroll is there.
There was a bit article somewhere, I think Yahoo! Sports, about Alabama football being on the verge of a real hammer drop for years now... and yet the NCAA won't go through with it.
Could KF leave Iowa for USC it wouldn't be the first Iowa coach to do so Howard Jones (I think), left Iowa for USC and won a national championships.
