I would choose OSU and USC if it was up to me.
I think OSU has to go based on record and regardless of what people think, they did beat PSU, Mich, and WA on the road. In a normal season, that's not much, but it is hard to make an arguement that someone played a tough schedule when they lost twice.
Picking the second team, I would say USC would be favored over Oklahoma who would be favored over LSU who would be heavily favored over Virg tech and Kansas.
