I can't see that happening. I can see one of two scenarios; play at the end of the season as normal or it's the last game of the SEC western schedule (if they go to the eastern teams to finish out the season.)
On the same note, consider what the draw will be for UA vs AU. If we look at the game being the last of the western games (11/7) the PAC only offers Cal vs Oregon (a projected upset for UO's only loss.) The ratings for a Bama vs AU game that day?
OR, if they push it to the last game of the season where we won't have a UF vs FSU game, or a UofSC vs Clemson game, or...another ratings bonaza.
