Ohio State is probably out now. Michigan is in barring a collapse against Iowa next week though even then maybe they can sneak in anyways as #4.
We'll see how the Championship Games turn out, but it's looking likely the rankings this week will be
1. Michigan
2. Georgia
3. Washington
4. Florida State
5. Oregon
6. Ohio State
7. Texas
8. Alabama
But Georgia-Alabama will be huge. If Alabama wins, that could cause some chaos. I still think Texas would have the edge over them since they do have the head-to-head win and are currently ahead of them too. If I had to guess, the 4 playoff teams will be Michigan, Georgia (unless they lose, which I don't predict), winner of Washington-Oregon, and Florida State. Texas, Ohio State and Alabama left out unless they get some help/upsets. I am interested to see how Florida State looks today + next week though with the backup QB. Sorry but I don't take their win over North Alabama seriously
