UGA gets in. Ohio State or Michigan if they win out. Cincy if they win out gets in.
I don't think anyone else can reasonably catch Alabama. They have the #1 SOS before even playing UGA.
Oklahoma and Oklahoma State even if they win out do not have the resume to get in. They have struggled to beat anyone handily. OKst barely beat a D2 team, Oklahoma only wins in close games and easily fails the eye test.
Notre Dame has the best argument, their SOS is 13th but they end with Stanford and will likely end up at about #20 and do not have a conference champ game so I would compare an 11-1 Bama vs a 11-1 ND.
If Bama gets blown out against UGA, that is the only scenario I see them being on the outs. Then I think Notre Dame likely fills in.
