As I look down the bowl schedule there are a handful of games with double digit or higher spreads, another handful that hover between 5-8 point spreads and then several that predict close games.
The biggest favorites are
Boise State -14
Texas A&M -9.5
I think those teams win their games pretty easily if they show up to play. I am not sure they all cover the spreads but I think they win. The next group is a bit closer
I think there are a couple of games in there that might go to the underdog. I think Kansas State may challenge Arkansas. I think Wisconsin will definitely challenge Oregon and who knows what kind of team shows up for Penn State. If they come motivated that defense is good and Houston hasn't played anyone.
