With wins by each of the top four teams this past weekend, the College Football Playoff rankings remain unchanged at the top ahead of an intriguing rivalry weekend slate of games.

Alabama, Ohio State, Michigan and Clemson continue to hold the inside track for spots in the PlayStation Fiesta Bowl and Chick-fil-A Peach Bowl.

The biggest game of this coming weekend will pit the Buckeyes against the Wolverines, while the Crimson Tide will play a stout Auburn team in the Iron Bowl. Clemson will face in-state rival South Carolina.

Also benefiting from Louisville's 36-10 loss to Houston (now ranked 20th), were Wisconsin, Penn State, Oklahoma, Colorado and Oklahoma State, which all moved up one spot and round out the top 10.
