Making the assumption (a big one) that there will not be any more "major upsets"...
If LSU wins the SEC:
LSU
Ohio State
Clemson
Bama
If UGA wins the SEC:
Ohio State
UGA
Clemson
LSU
Oregon, Utah, Penn State, and Oklahoma all have an outside shot, but several dominos would have to tip their way. Minnesota and Baylor will not finished undefeated, and the late loss(es) will knock them down or out of the top 10. Bama gets in as a 1-loss team to an undefeated LSU. If UGA gets to the SECCG and wins it, then LSU gets in as a 1-loss team to the SEC Champion. If any of the top 5 I listed drop another game, then it opens the door for one of the next 4 in line. But if not, the field of 4 will come from the field of 5 I listed.
Go Vols.
