Ohio State won't fall any further than 3. That's a given. And obviously it doesn't matter if it ends up 2 or 3, they play Clemson. OU can't be any higher than 4. They just need to be content they snuck in. Now if Wisconsin were not only to win but win convincingly, do they jump OU? They avenge their only ugly loss of the season. It's not out of the question, but it is still highly unlikely.
