I don't think you have to worry about LSU showing up to play. This game is probably going to come down to the wire and may even go into overtime, Les and Saban have played 3 overtime games since 2007.
I think Leonard understands that if he wants that coveted Heisman Trophy (coveted for players) he is going to have to show up tonight. This game really was the game that killed Tyrann's Heisman run, he just didn't do much.
