I always pull for the SEC team against outside competition, especially in bowl games. Doesn't mean I can stand to watch 'em play, though. I just check the scores frequently. As far as I'm concerned, they each represent my team's conference. I apply my Scotch-Irish heritage to the SEC: we'll fight each other until an outsider comes along, but then we become family again.
As for Nat'l Championship games... if I'm in a crowd that's pulling for the non-SEC representative, I'll watch and cheer (even Bama). But when it was Florida, I think I just made an excuse and went home. I do have my dignity.
I remember when Bama was a classy rivalry (between the players). Bitterly fought on the field, but all mutual respect when the game ended. That should continue.
All teams in Florida have been class-less since Schnellenberger left Miami, and the Gators have been the worst. I really resent any time they represent our conference. I'd rather bring back Ga Tech and banish the Gators to the ACC.
