LSU reached No. 1 the hard way.

The Tigers edged past Southern California in the AP Top 25 on Sunday, even though the Trojans remained undefeated.

On a wild day in college football, when half the top 10 lost, USC avoided the upset bug that struck Oklahoma, Florida, Texas and Rutgers. But a sloppy 27-24 victory at Washington on Saturday night cost the Trojans the No. 1 ranking they've held all season.
USC is the first team to lose the No. 1 ranking after a victory since Nov. 3, 2002, when top-ranked Miami dropped after beating Rutgers 42-17 and No. 2 Oklahoma moved up after a 27-11 victory over No. 13 Colorado.
LSU, which recovered from its own first-half malaise to beat Tulane 34-9 on Saturday, received 33 first-place votes from the media panel and 1,593 points. USC got 32 first-place votes, 11 fewer than last week, and 1,591 points. The voting was the closest since the second poll of the 2002 season,
