It would be an interesting conversation if UGA, UM, and Cincinnati all win. Your likely contestants for the final Playoff spot would be:
Notre Dame - Went 11-1, with only loss to Playoff team. However, no conference title and no wins over a Top 25 team.
Baylor- Power 5 Conference Champion. 3 wins over Top 15 teams. However, two losses, including a loss to a losing team (TCU).
Alabama - SEC West Champion with only losses to Top 25 teams (including to top team in country). However, two losses, and no conference title.
I can't imagine that Ohio State (2 losses, not even in conference title game), Ole Miss (see Ohio State), or Oklahoma State (just lost to Baylor) would get much consideration.
Now, what would be real chaos is if Michigan falls on its face.
