New York ? No doubt about it, LSU is No. 1.

As for the rest of the Top 25, five wild weeks of college football have taken quite a toll.

The Tigers were a unanimous choice for the top spot in The Associated Press rankings released Sunday, receiving all 65 first-place votes from the media panel. The last unanimous No. 1 during the regular season was Ohio State in December.

LSU is one of just four teams that started the season ranked in the top 10 and remain there. The others are No. 6 Oklahoma, No. 8 West Virginia and No. 10 Southern California, which became the latest team to take a tumble after a startling loss to an unranked opponent.

The Trojans fell to Stanford 24-23 on Saturday, then dropped eight spots in the rankings.

California is the new No. 2.
