I think we should all be pulling for Penn State...
If we can make it to the championship game, I'd much rather play Penn State than USC, Texas, Oklahoma, or just about any other possibility.
Plus, any college football lover should do anything it takes to keep Ohio State out of the discussion of getting to the title game. Especially if USC is the other team.
I meant to add... Penn State losing a game will not likely do anything to our chances of getting to the title game.
If we go undefeated, we're in. If we lose a regular season game, but win the SEC championship, we'll be in over a one-loss Penn State. If we lose the SEC championship, we're not going anyway.
