Their only real tests are Auburn and Clemson. If they won the SEC, they're obviously in. Depending on what else happens with FSU, Oklahoma, Oregon, I think they could sneak in at 11-2 if they lost a close one in the SEC championship game. The SEC West is gonna eat itself. Auburn(who also plays GA), LSU, Bama, TAMU play each other. A couple of them will have 3 losses. That said, SC will lose a game that they have no business losing. They seem to do it every year so it wouldn't surprise me if GA reps the East in the SEC championship against a 1 loss Bama/Auburn.
Damn. I forgot about Ole Miss. SEC West is tough.
