USC lost to Oregon State. Michigan lost to Ohio State AT Ohio State by 3, which is the amount oddsmakers give to the home team. I think w/o question it should be Michigan and let them play at a neutral site.
I don't think that's particularly fair though. If Michigan wins the rematch it's still just 1-1 on the season. Is there a rubbermatch after that? Why should Ohio St. lose out on the NC because of the difficulty involved in beating a team twice in one season?
Not a big fan of rematches. I agree with Tressel when he said (pre-game) the two teams in the NC game should have won their respective conferences.
Either USC (if they beat Notre Dame) or then the winner out of Arkansas/Florida (assuming both go into the SEC championship game with only 1 loss).
