I see a path for Alabama
1. Georgia goes undefeated
2. Ohio State beats Michigan by 14
3. TCU goes undefeated
USC gets beat by Notre Dame. USC lost to Georgia giving them 3 losses. That leaves it to the committee to choose between Clemson, Michigan, and Alabama.
Alabama has two losses, both of them close, in by far the toughest conference in the country.
Michigan is only one loss, but does losing to Ohio State do them any favors (insert OSU if Michigan beats them by 14).
Clemson only has one loss, but it was ugly. Their strength of schedule does them no favors.
