LSU flip-flopped with Alabama on Sunday to become the new No. 1 in The Associated Press poll. The Tigers received 1,476 points, two more than Alabama, for the closest margin between Nos. 1 and 2 since No. 1 Florida State was two points ahead of Auburn on Oct. 5, 2014.

No. 3 Ohio State was not far behind with 1,468 points. Eight points separating first from third is the fewest in the regular season since Dec. 3, 1979, when No. 1 Ohio State was 10 points ahead of No. 3 Southern California, with Oklahoma in between, two back of the Buckeyes.

Alabama received the most first-place votes this week with 21. LSU and Ohio State both got 17 first-place votes. No. 4 Clemson received seven first-place votes.

The Alabama-LSU game is scheduled for Nov. 9 in Tuscaloosa, but the top of the rankings should be locked until then. LSU, Alabama, Ohio State and No. 5 Penn State are all off this week, and No. 4 Clemson is tuning up against Wofford.

Oklahoma became the third top-six team in the last three weeks to lose to an unranked team, falling at Kansas State and dropping five spots to No. 10.
