I agree that it's generally harder for TCU than the current big names, but a 1 loss TCU with a win over buckeyes would be in an outstanding position to make the invitational.
We’ll be a lock next year with 1 loss and a Big 12 championship. Heck, even without playing Ohio State we’d have been a lock this year. The idea that we can’t lose a game and make the playoffs is just so dumb
