Both TCU and Bama have beaten Texas, and TCU just lost on a neutral field to the other good team they beat earlier in the season.
Bama was beaten on last second scores twice. Both were road games.
Tennessee isn't even considered because of the loss of Hooker.
Bama is a better team right now than TCU.
I'm not a Bama supporter, I'm just telling you that they are the 4th best team in the country. However, IMO Georgia and Michigan are head and shoulders above everyone.
And, having said all of that....TCU will still get in because the Big 12 will be given a seat at the table.
