One week after Texas leapfrogged USC in the BCS standings, the Trojans returned the favor, taking over the top spot in the most recent standings.
It was the first time in the history of the BCS that the No. 1 and 2 teams have flip-flopped in consecutive weeks.
The Longhorns actually improved their standing in the six computer polls used in the BCS formula. Last week, Texas was No. 1 in five of the computer polls; this week, the Longhorns hold down the top spot in all six.
But USC solidified its hold on No. 1 in both the Harris Interactive and USA Today polls, likely helped in part by Texas' struggles against Oklahoma State. The additional votes allowed the Trojans to take a .0038-point lead over the Longhorns.
But neither USC nor Texas can relax too much, because Virginia Tech is starting to make its move. Buoyed by their surprisingly easy win over Boston College, the Hokies picked up additional votes in both the Harris and USA Today polls and caught USC in the computer rankings.
As a result, Virginia Tech is now just .0435 points out of second place; last week, the Hokies were .0592 points behind then-No. 2 USC.
And with another opportunity to impress both the human voters and the computers looming this week in the form of Miami, Virginia Tech could be poised to cut further into Texas' lead.
Alabama and UCLA each moved up one spot -- to fourth and fifth, respectively -- after Georgia's loss to Florida dropped the Bulldogs down to 11th.
They are followed by Miami, Penn State, LSU, Florida State and Ohio State.
Notre Dame, which must finish with nine wins and be ranked at least 12th in the final standings to be eligible for at-large consideration, moved up one spot to 14th.
