Bama's essentially eliminated from the SECCG because LSU will be prohibitive favorites in their last 3 games (including Arkansas how may be the worst Power V team in the country), and LSU could lose 1 and still hold the tie-breaker over Bama. Unless a conference champion has two losses, will be hard to take a non-conference winner, who didn't make the their conference championship game over a one loss conference champ like OU or the Pac 12 champ. Also, think there is some Bama fatigue and the committee has generally favored teams who play a legit OOC opponent which Bama did not do.
The path for two SEC teams is not with Bama, but for LSU to finish 12-0, and lose a close game to UGA in the SECCG. In that scenario, the SEC probably would get two as LSU would have more quality wins than anyone else (including a win over Bama) and only one loss.
