The only picks I'm gonna disagree with you on is the Big XII title game and Rutgers-WVU. For some reason, I like Nebraska in the Big XII and I'll get to the ACC in a minute.
As for the SEC game, I don't think Florida's offense, which has looked lousy the last few weeks, will be able to keep up with Darren McFadden and Arkansas.
Wake looks like a team of destiny in the ACC, and Georgia Tech is also struggling on offense; while in the Big East, I think West Virginia bounces back from the upset last week and knocks off Rutgers, sending Louisville to the Orange Bowl.
Finally, as big an Army guy as I am, I don't see them being able to stay with Navy for 4 quarters.
nah...
I think 20 points is a lot to cover for Navy, but I don't think this game will be really close.
