No I do not buy that UM OSU should play again. I NEVER think the NC game should be a rematch of an earlier game in the season.
First of all, UM has not beaten any real competition but ND. Yes the killed them, but I would like to see them play some other team to get a real gauge on how good they are.
We know OSU is better than UM. I really don't think anyone doubts that. So why not see them play a tough team from a different conference. AT least solve the debate of one other team (USC, Ark, UF - IMO only three that should be there).
IF the NC game is a rematch, I for one will not watch. I may be alone in that, but I'd rather go to a movie with my wife than watch a 're-run'.
