because their champ(s) doesn't have 12 wins.
If FSU lost, they're not getting in.
If Oregon lost, I could see UCLA jumping them, but not ASU or Arizona. If Stanford somehow beats UCLA, then Oregon is the PAC-12's only shot. But, Oregon is out with a 2nd loss.
If Alabama somehow lost, they could still get in but just barely.
If Ohio State lost, they're not getting in and neither would Wisconsin.
