Michigan, because it may mean more than Oklahoma, but if you would have asked me at the start of football season, I would have said Oklahoma without a doubt.
OU. I've never seen it happen, and it could propel the team forward and potentially help get another win. Also, I think we'll have a good year in basketball regardless of if we beat Michigan or not.
Oklahoma, but only if you told me that we would lose by 5 or less to Michigan. As others have said I have never seen us beat OU in my lifetime and I think beating them in Norman could potentially help negate the negative aspect of this season as well as propel us to at least one more win to finish the season.
We still have a lot of potential to create an excellent tournament resume for basketball and no way a close loss to a top 10 team would hurt much.
