I'm just not on board with this line of reasoning. Here's why:
All we've heard before the LSU/ALA game is Bama better not lose to LSU because of how weak their schedule is. That changed after the game because what most folks thought they saw was a great LSU team, who has quality wins, get pushed to the limit by a hobbled Bama team.
But if LSU loses to Ole Miss, I think it makes our loss to LSU look like the pre-LSU/Bama prognosticators were right in the first place.
I could be wrong, but I fully believe our best chance to get into the playoff (assuming we finish 11-1) is to have LSU sitting there 13-0 after winning out, including the SECCG.
FWIW, the idea that LSU loses two games to put us back in the west drivers seat is slim to none, IMO.
