One of the biggest weekends of the season produced the most upheaval yet in the Rivals.com College Football Power Rankings.
More than half the No. 1 spots changed hands in the latest edition of the power rankings, which measure the nation's top players and coaches at each position.
The biggest game of the week – Texas' 45-35 victory over Oklahoma – caused plenty of the shakeups in the rankings. Oklahoma's Sam Bradford was the losing quarterback, but his consolation prize was a move atop our rankings. Bradford was 28-for-39 passing for 387 yards with five touchdowns and two interceptions against Texas. That performance moved him ahead of Missouri's Chase Daniel, who threw three interceptions in a 28-23 home loss to Oklahoma State.
Bradford also was sacked twice by Texas defensive end Brian Orakpo, the new No. 1 defensive lineman. Orakpo replaced South Florida defensive end George Selvie, whose team was idle last weekend.
Michigan State's Javon Ringer regained the top spot at running back from Ohio State's Chris Wells in what could develop into a back-and-forth battle all season. Ringer rushed for 124 yards and two touchdowns on 35 carries in a 37-20 victory over Northwestern. Wells ran for 94 yards on 22 carries and didn't score in a 16-3 triumph over Purdue.
Penn State gained a monopoly atop the coordinator rankings after the Nittany Lions' 48-7 rout of Wisconsin. Penn State's Galen Hall took the No. 1 spot at offensive coordinator from Missouri's Dave Christensen.
The rating of a player and coach can fluctuate each week during the season depending on how they fared the previous week, but the power rankings measure overall career performances as well as their most recent results.
