re: If LSU and Tennessee both win out...

LSU and Georgia should get in, if that happens I would bet the final rankings look like this:

1. Michigan (13-0)
2. Oregon (12–1)
3. LSU (11-2)
4. Georgia (12-1)

Or

1. Ohio State (13-0
2. LSU (11-2
3. UCLA (12-1)
4. Georgia (12-1)

I doubt TCU goes 13-0 and if the PAC 12 champ has 2 losses none of them will get in either. An 11-1 Michigan or OSU will not get in over an 11-2 SEC champ LSU.
