I agree I think the over might be the play.
What scares me about backing Penn State is their pass defense and the turf. Penn State does not play a lot on turf and if Wisky throws the ball a lot they could outscore Penn State.
IMO Penn State is definitely the better team, they were very flat the first three quarters against Iowa. I see them being focused for this game. They are still in the Big 10 race with a win vs. the Badgers.
If I had to play the side in this game it would be Penn State but if the total is 56 or less it might be an over play for me.
