NEW YORK — Texas A&M makes a big jump in the AP Top 25 after the most impressive performance of the opening weekend of college football. Florida State and Alabama lost some support in the first poll of the regular season after close victories against heavy underdogs.

Meanwhile, BYU moved up to No. 35 in the poll (21 points). The Cougars opponent on Saturday, Texas, is knocking on the top-25 door. The Longhorns check in at No. 26 with 126 points, 15 behind Louisville.

The Aggies moved up 12 spots to No. 9 in the poll released Monday. Texas A&M began the post-Johnny Manziel era with a 52-28 victory at South Carolina. The loss dropped the Gamecocks from ninth to No. 21.

The top four in the rankings are unchanged: Florida State, Alabama, Oregon and Oklahoma.

Florida State went from 57 first-place votes to 46 after pulling out a 37-31 victory against Oklahoma State.

Alabama dropped 44 points in the media-panel voting after beating West Virginia. The Tide has one first-place vote. Oregon has five and Oklahoma two. No. 6 Georgia has two and No. 12 LSU one.
