My guess is that the stadium will be rocking louder than ever.  It'll be a return to normalcy for the fans; a chance to move on.  And as somebody else mentioned, the players will look at the season as if they have 12 bowl games on the schedule.

Certainly if you've played - and probably if you've watched - an appreciable number of games, you might agree that it is just plain impossible to predict with any consistency how pumped or flat a team will be for any game. 

I put the Ohio-Penn State game in that impossible-to-predict category.  Sure, the Lions could start out roaring.  Or they could have to force themselves to snarl now and then.  Or, thanks to a rush of adrenalin, they could start out roaring and then fade by the second quarter.  Even in the locker room or during pre-game warmups, players might not know how they will perform after the opening kickoff.
