Change among the top four in the College Football Playoff rankings released Tuesday was anticipated with No. 2 Ohio State and No. 3 Michigan playing each other in Week 13. The only possibility of the leading quartet occupying the first four positions - albeit in a different order - was if the results of the Big Ten showdown was close.
However, the result was not close and the Buckeyes paid the price, dropping all the way to fifth and are on the outside of the playoff field with one weekend left.
At the top, Georgia holds at No. 1 for the fourth consecutive week. Michigan moved up one spot to second. TCU did as well to take third. Those are the three remaining unbeatens left in the Bowl Subdivision. Each should confirm their spot with wins in their respective conference championship games this week and it's possible one or more could afford a loss given the lack of strength among the contenders behind them.
Southern California now occupies fourth after its defeat of Notre Dame. The Trojans, who were sixth last week, were also helped by LSU surprise loss to Texas A&M that sent the Tigers tumbling to 14th. A win against Utah in the Pac-12 should confirm their selection to the playoff for the first time.

That leaves Ohio State followed by Alabama needing chaos to somehow wiggle their way into the field. The Buckeyes - with one loss - have the best opportunity to break things up. The two-loss Crimson Tide might already be effectively eliminated. Tennessee, Penn State, Clemson and Kansas State complete the top 10.
No. 18 Tulane leads all teams from the Group of Five. The Green Wave host No. 22 Central Florida in the American Athletic championship game with the winner almost assure a place in the Cotton Bowl.
