If it was JUST on the field performance, I'd take Georgia, Bama, Michigan, tOSU
BigTen vs SEC .... probably SEC winner vs BigTen East #2, and BigTen East winner vs SEC Runner up....
I don't think Cincy or Oklahoma or Oregon are better than those teams right now ... and the Runner Up from BigTen and SEC would win handily the AAC, the PAC-12 and/or the BigXII.
