Clemson and Alabama retained the top two spots in the Associated Press Top 25 as Big Ten and Pac-12 schools rejoined the poll released on Sunday.
The top-ranked Tigers (2-0) received 55 of 62 first-place votes, with three votes going to the No. 2 Crimson Tide (1-0) and four to No. 6 Ohio State (0-0).
No. 3 Florida (1-0) moved up two spots, No. 4 Georgia (1-0) held steady and No. 5 Notre Dame (2-0) also climbed two positions.
After the Buckeyes, the rest of the top 10 features Auburn (1-0), Miami (Fla.) (3-0), Texas (2-0) and Penn State (0-0).
Also rejoining the poll were No. 14 Oregon (0-0), the only Pac-12 team in the Top 25, and two more from the Big Ten: No. 19 Wisconsin (0-0) and No. 23 Michigan (0-0).
Mike Leach and No. 16 Mississippi State (1-0) joined the poll after Saturday's 44-34 win against LSU. The defending national champion Tigers (0-1) plummeted from No. 6 to No. 20.
The week's biggest drop, however, belonged to No. 18 Oklahoma (1-1), which fell 15 spots after a 38-35 loss to Kansas State.
Six schools fell out of the Top 25: Marshall, Louisville, Army, Louisiana, Virginia Tech and Kentucky.
