How they can make the playoff: Up until this point, it felt as if TCU needed to go undefeated to make the playoff. However, as other contenders have fallen, the Horned Frogs are looking close to a lock now. Given that they will face a top-15 opponent (Kansas State) in the Big 12 championship game, even a loss there wouldn't be the end of the world: A single loss and conference runner-up would probably still be enough to keep them ahead of Ohio State and Alabama.
