The Florida Gators needed three quarters to get their footing at a rainy Williams-Brice Stadium in Columbia, South Carolina. But their finishing kick delivered a knockout blow to South Carolina. It may have also helped Florida knock on the door of a College Football Playoff berth. Or at least the outskirts of the conversation.

Florida is the top one-loss team in the nation at No. 7, jumping Notre Dame following Florida's 38-27 win over South Carolina on the road. The Gators enter their bye week before a Nov. 2 showdown with No. 10 Georgia with an eye on the standings and the teams ahead of them.

Ohio State edged past Clemson to No. 3 in The Associated Press college football poll and Wisconsin dropped to 13th after being upset ahead of its showdown with the Buckeyes.

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.

UCF received three votes in the poll once again after a 41-28 win over ECU. The Knights will have plenty of competition to climb over if they want to find themselves in a New Years Six bowl game, let alone the American Championship Game, for a third straight year.

Boise State's loss to BYU has thrown the race to be the top Group of 6 conference team into turmoil. SMU now appears to have the pole position at No. 16 in the AP Poll with Cincinnati (No. 18), Appalachian State (No. 21) and Boise State (No. 22) still taking up spots in the poll. The Knights essentially would have to win out and hope for losses from Cincinnati, Appalachian State and Boise State to have a chance at a third straight bid.
