New York Texas rode its resounding Red River Rivalry upset right to No. 1.
The Longhorns leapfrogged No. 2 Alabama on Sunday and sit atop the Associated Press Top 25 in the regular season for the first time in 24 years after beating Oklahoma, 45-35.
Texas' jump to No. 1 is the largest since Miami went from No. 6 to No. 1 on Aug. 29, 1988, after beating preseason top-ranked Florida State, 31-0, to start the season.
Texas received 39 first-place votes and 1,599 points from the media panel. Alabama received the other 36 first-place votes and 1,582 points.
"Being ranked No. 1 shows respect for what we've accomplished through the early part of the season, but nobody really knows who is No. 1 at this point," Texas coach Mack Brown said.
The Longhorns are the fourth No. 1 team this season, following Georgia, Southern California and Oklahoma. So it's just more of the same following an unpredictable 2007 season that had four No. 1 teams and eight different teams ranked second.
