Penn State has climbed to No. 2 in the Associated Press poll behind unanimous No. 1 Alabama after a wild weekend of upsets gave the Top 25 a major makeover.
A season-high seven ranked teams, including four in the top 10, lost to unranked teams on Friday and Saturday. Defending national champion Clemson and defending Pac-12 champion Washington were the highest-ranked teams to lose.
Penn State, which was idle, took advantage. The Nittany Lions moved up a spot to No. 2, 15 points ahead of No. 3 Georgia. Penn State has its best ranking since Oct. 31, 1999, when the Nittany Lions were No. 2.
Alabama, which has been No. 1 since the preseason, received all 61 first-place votes for the first time this year.
The Big Ten leads all conferences with five ranked teams. The ACC, SEC, Big 12 and Pac-12 each have four, while the American posted three ranked teams. Independent Notre Dame rounds out the Top 25 at No. 13.
