U of O is by far the worst team in the Pac-10 this year. Not that OSU is good, but they are definitely better than the Ducks. Having said that, I wouldn't feel comfortable taking a bad team like the Beavers on the road in a rivalry game like this. Something tells me OU wins and covers since they're at home, it's against their biggest rivals, and it's their last game of the season, but there is very little talent on that team so I won't be playing them.
GL with whatever you play.
