here is his take:
Sherrington: Are you saying that Oklahoma is being snobby academically with the SEC and they don't want the competition in football?
Tramel: "
I would say the latter is more true. I don't think they're being snobby. I think they look at the Pac 12 as a way to enhance their academic reputation. SEC is about the same as the Big 12. Big 12 used to be better and then the SEC got two of the better academic institutions from the Big 12 and sort of tilted it. But I think they'd rather be in a league with Stanford and Cal and UCLA than in a league with Mississippi State or Georgia."
