One caveat I'll throw in: I think if LSU wins out, they're in. Yes, 2 losses, but winning the best conference in the country and beating Bama & UGA (in the SECCG) IMO gives them a spot.
It would definitely put the committee in a tough spot. Don't forget about Tennessee, they beat Bama and whooped LSU @Death Valley. The pitchforks will be out if they chose LSU over Tenn in that scenario.
The committee will definitely be rooting for LSU or Tenn to lose again.
