Alabama remained No. 1 on Sunday in the AP Top 25 presented by Regions Bank, receiving 24 first-place votes. No. 2 LSU held its place and received 16 first-place votes. The Buckeyes had 13 first-place votes and No. 4 Clemson, the preseason No. 1 team and defending national champion, received nine.
The Buckeyes and Tigers both were coming off conference blowouts on the road. Ohio State beat Northwestern 52-3 Friday night. Clemson defeated Louisville 45-10.
The point margin between the No. 1 and No. 4 in this week's Top 25 is 78, the smallest it has been this season. Alabama received 1,486 points while LSU had 1,462, Ohio State had 1,429 and Clemson had 1,408.
Oklahoma remained No. 5, but Penn State moved up to sixth after Wisconsin's first loss of the season. The Badgers were beaten Saturday by 30-point underdog Illinois in the season's most significant upset so far.
Florida, Notre Dame, Auburn and Georgia round out the top 10, giving the Southeastern Conference five of the top 10 teams.
Preseason No. 1 teams commonly relinquish the top spot without losing, but the extent of Clemson's fall is unusual. The last preseason No. 1 to drop as far or farther without a loss or tie was Oklahoma in 1977. The Sooners slipped from first to fifth after opening the season with a 25-23 victory over Vanderbilt. Oklahoma started climbing the very next week and reached No. 1 again before losing its fifth game of the season to Texas in mid-October.
One has to go all the way back to 1971 to find a similar drop to Clemson's for a preseason No. 1. Notre Dame started that season top ranked and won its first five games, slipping to No. 7 while doing so. Maybe voters' suspicions of the Irish were justified: Notre Dame lost twice in the second half of the regular season to finish 8-2 and ranked No. 13.
That Notre Dame team seemed to suffer from a schedule perceived to be not so rigorous and one very close victory. None of the Irish's first five opponents was ranked at the time of the game and Notre Dame beat Purdue 8-7. Those Boilermakers went on to finish 3-7.
Clemson has played just one team that was ranked at game time, then-No. 12 Texas A&M, which has since dropped out of the rankings. And the Tigers had a one-point victory at North Carolina, which is currently 3-4.
No teams are making their season debut in the Top 25 this week, but a couple re-entered.
— No. 23 Iowa State (5-2) is back after winning three straight games.
— No. 25 Wake Forest (6-1) returns after a one-week hiatus. The Demon Deacons bounced back from their first loss of the season last week to beat Florida State on a late field goal.
— Missouri is the latest team to lose right after moving into the Top 25 for the first time this season. The Tigers were upset by Vanderbilt.
— Washington is out again after losing a thriller to No. 11 Oregon.
Big Ten — 6 (Nos. 3, 6, 13, 17, 19, 20)
SEC — 5 (Nos. 1, 2, 7, 8, 10)
Big 12 — 4 (Nos. 5, 14, 15, 23)
Pac-12 — 3 (Nos. 11, 12, 24)
American — 2 (Nos. 16, 18)
ACC — 2 (Nos. 4, 25)
Mountain West — 1 (No. 22)
Sun Belt — 1 (No. 21)
Independent — 1 (No. 8).
