When all the top teams in the win or don't play, there isn't much mystery about the next College Football Playoff rankings release. But that doesn't mean there wasn't some things worth noting in the fourth reveal of the season after an uneventful Week 13.

First, let's start with the obvious. Ohio State retained its position at No. 1 ahead of its matchup with Michigan. The Buckeyes must win to guarantee a spot in the Big Ten title game with the likely opponent being No. 2 Indiana, which has held that spot since the first rankings.

Texas A&M, the other remaining Bowl Subdivision unbeaten, remains third followed by Georgia and Texas Tech. The Aggies can lock up a spot in the SEC title game with a defeat of Texas.

The second part of the top 10 had one change. This group has some danger ahead of Week 14. No. 6 Oregon - up one spot - faces a tricky test at Washington. No. 7 Mississippi, which drops one spot, heads to rival Mississippi State and Oklahoma is eighth and must finish off its SEC gauntlet by beating LSU. Notre Dame and Alabama occupy the last two spots for at-large teams with the Crimson Tide also going on the road against its biggest rival - Auburn.

Lurking outside the top 10 are the next five of Brigham Young, Miami, Utah, Vanderbilt and Michigan. The Cougars can still control their destiny by winning the Big 12 while the others are poised to potentially join the field with some help in the final two weekends. It's notable the Hurricanes are three spots behind Notre Dame - a team that they beat in the opener. A win against No. 22 Pittsburgh could boost Miami closer and possibly knock out the Fighting Irish.
