But Utah will have played only one (Oregon). Oregon will have played two, but with one loss and potentially one win. Advantage OU. And with their advantage in the helmet sticker department, I think they would get in over Utah or Oregon.
But, it may come down to OU or Alabama, each with one loss. I could definitely see the committee going with Alabama there with wins over Auburn, aTm, and a close loss to LSU. But with Tua out, who knows how they will view them.
