There was some significant movement in the new rankings released after the Week 13 games. While the top four teams in last week's rankings —Oregon, Ohio State, Texas, and Penn State—all took care of business, other teams projected to be in the 12-team College Football Playoff bracket suffered losses.

The College Football Playoff selection committee released its fourth top-25 rankings of the season ahead of the first 12-team playoff, and unsurprisingly, the Oregon Ducks are still the No. 1 team. Only one more edition before the final rankings on Selection Sunday.
