I think it will come down to Bama and Buckeyes (provided the Bucks win) ... Bucks have the better resume.
If they get in, thats why.
How?
They both have one loss to a top team.
Yet Ohio State got blown out by a three loss Iowa (no offense to Iowa).
Other than that, the schedules arent that dissimilar.
To me it comes down to one loss to two. With a win over Wisconsin OSU has an argument.
Although on resume alone I think bama does as well. That Iowa loss is a big negative.
That said I don't think bama is playing good enough that if it were decided right now that they should be in. And I'm not sure who should be.
At playoff time however much of what's made us beatable will be resolved. Our defense should be healthy.
