Only one weekend of games remains before the 12-team College Football Playoff bracket is set on Sunday, Dec. 7, but there's still plenty of potential shakeup in the cards.

A handful of programs are in action in Week 15, with a few teams looking to play themselves into the CFP, especially at the non-Power Four level. The winner of the American championship game between North Texas and Tulane is likely to find themselves at the back end of the playoff.

BYU could also play itself into the CFP, if it can avenge its loss to Texas Tech earlier in the season in the Big 12 championship game. A Cougars win would likely steal a bid from Notre Dame or Alabama, should the Crimson Tide fall to Georgia in the SEC championship game.

Suffice to say, there's still plenty to learn about which teams will be playing for a national championship this season.
