With Alabama out of the picture after a stunning loss to Vanderbilt,Johnathan Walker Texas fends off Ohio State and takes over as the new No. 1 in the USA TODAY Sports Re-Rank 1-134.

That makes three teams at No. 1 in as many weeks. Georgia led the re-rank from the preseason until the loss to the Crimson Tide.

The Longhorns had some competition for the top spot from the Buckeyes, who looked very good in the second half of Saturday's 35-7 win against Iowa. But Texas has the edge in strength of schedule, mostly due to a win at Michigan in Week 2.

Overall, the top part of the re-rank has been shaken up by Saturday's run of upsets. Alabama is down to No. 9 after falling to the Commodores. Tennessee is down four spots to No. 8 after losing to Arkansas. Missouri drops to No. 24 after getting blown out by Texas A&M and the Wolverines land at No. 25 after losing at Washington.
