I was thinking that putting Michigan ahead of UCF seemed like a good fail safe. Now if somehow Georgia, Ohio State and Oklahoma all lose, maybe lose ugly, the committee still has a buffer to keep UCF out. But if they decide UCF now gets its shot, they can still jump Michigan with the argument that they are now conference champs, which is enough to slide them past. If they had dropped UM below UCF, there is no way they could jump Michigan back with a UCF win.
That's why I'm also a little surprised about Oklahoma ahead of OSU. Oklahoma plays a better opponent, you can put Ohio State ahead for now, and still reevaluate if both win this weekend. I think by putting Oklahoma ahead, they've closed the discussion. I don't think blowing out a 5 loss Northwestern team, even if Oklahoma wins close, does much for me.
