The Texas A&M Aggies, buoyed by their victory over South Carolina, moved up 12 spots to No. 9 in the AP Top 25 after the opening weekend of college football.
The top four in the rankings -- Florida State, Alabama, Oregon and Oklahoma -- are unchanged, but the No. 1 Seminoles and No. 2 Crimson Tide lost some support in the first poll of the regular season after close victories against heavy underdogs.
Texas A&M began the post-Johnny Manziel era with a 52-28 victory at South Carolina. The loss dropped the Gamecocks from No. 9 to No. 21.
Georgia, led by running back Todd Gurley, rose six spots to No. 6 -- even earning two first-place votes -- after a 45-21 victory over then-No. 16 Clemson, which tumbled seven spots to No. 23.
Florida State dropped from 57 first-place votes to 46 after pulling out a 37-31 victory against Oklahoma State. Meanwhile, Alabama dropped 44 points in the media-panel voting, getting just one first-place vote, after beating West Virginia.
Oregon received five first-place votes, Oklahoma had two and No. 12 LSU got one after rallying to beat then-No. 14 Wisconsin, which fell four spots in this week's poll.
Louisville was the only new team in the poll, entering at No. 25 after beating Miami 31-13 in the Cardinals' ACC debut.
