I would love to play LSU in Provo. Memories of '90 all over again. But like you said, no way it would happen. As for playing them there, it would be a great game for us and our players. If we were to lose, our margin for error the rest of the season would be greatly magnified. I don't think we'd get a BCS bid with any other losses, unless the season as a whole is similar to this year.
Compare that to our schedule now, and it probably isn't too far off.
