Penn State has climbed to No. 2 in the Associated Press college football 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, with the Tigers falling from No. 2 to No. 7 and the Huskies dropping from No. 5 to No. 12

Also from the Big Ten in the top 10 are Wisconsin at No. 5 and Ohio State at No. 6.
