Agree with the poster who mentioned that it comes down to coaching. The SEC is where you have the greatest depth of good coaches. They do spend an disproportionate amount on their coaches, facilities, and have also had their success augmented by the mostly easier admissions standards. Factor in that places like Bama were oversigning at an extremely high rate relative to other schools, and you have your reasons for success.
I have no doubt that Miami or FSU could knock off the SEC. You don't need to to have the "beat your asses and steal your GFs" attitude either. Butch's teams didn't have that. They just were physically and mentally better. That comes from coaching and S & C. I suspect that Golden can do it. It's going to take a few years, but if he can make the right changes to the S & C program and tweak a position coach here or there, I think he'll be on his way. His level of organization, work ethic, and drive, are stronger than Butch's when he first got to Miami. He's shown he can win at other places, and there's no reason to believe he won't at Miami.
As for USC, I think Oregon will continue to be a thorn in their side. I'm not sold on Kiffin. I think he, himself, is a liability. He tends to have self-destructive tendencies. I don't see them having the same success they had under PC. They were Miami West when PC was around. Kiffin is < PC.
Had Harbaugh stayed, I think Stanford would have been a legit team annually with a good enough team to beat the best of the SEC. Without him and without Luck, I don't see them being able to maintain their success.
Finally, Texas could certainly do it. They have the players for sure. If Brown retires, and they sign say Patterson. They'll be nasty.
Ohio St under Meyer could do it. Michigan finally has a nice trio of coaches in Hoke, Mathieson, and Borges. They just need to get the right players. I'm not sure if they're up to that caliber, but I do like that coaching staff.
