The way I think it would go, is that a B1G and SEC Champ with one loss or less is in no matter what. A one loss ACC Champ Clemson is also most likely in, and undefeated most certainly is. So in this plus the original scenario, you have Alabama, Ohio St/Michigan and Clemson in. Assuming best case for all the other teams (which we know won't happen), you have UGA, Tenn, Michigan/Ohio St, TCU, UCLA competing for the last spot. I think UGA would be ahead of Tenn due to the H2H, and they would be ahead of TCU and UCLA due to SOS and it's going to be really hard for the committee to look past that opener against Oregon. So then you have UGA vs a 1 loss Ohio St or Michigan, and I think UGA gets the nod there too by virtue of having played in a conference championship game.
But I expect there to be further chaos this season. For instance, Tenn loses to UK but beats UGA. Or Ole Miss beats Alabama but loses to Miss St and LSU. Ohio St inexplicably losing to Iowa or some crap. It should be a fun last 6 weeks
