2000s: Top 10 College Football Upsets

Oklahoma's vaunted defense had carried it to a 12-0 season and No. 1 ranking, but upset-minded Kansas State shredded the normally stingy unit. Ell Roberson threw four touchdown passes and Darren Sproles recorded 235 rushing yards, and the Sooners, who had trailed for all of six minutes the entire season, found themselves on the wrong side of a blowout. They didn't fare much better on offense, as constant pressure from K-State's front four led to a two interception, zero touchdown effort from Heisman contender Jason White. The win earned the Wildcats their first BCS berth and put the Sooners' national title-game worth in doubt, but they ultimately earned the berth over eventual co-champion USC.
