Editor's Note: Tom Murphy is one of 61 voters in the Associated Press Top 25 poll. Each week, he reveals his ballot and offers insight into his votes.
No changes in the top three of Alabama, Georgia and Clemson.
Ohio State jumped two spots to No. 4 after downing TCU 40-28. The Buckeyes displaced Oklahoma, which fell to No. 5 after surviving an upset bid at Iowa State.
Wisconsin dropped 12 spots to No. 17 after falling at home to BYU. TCU fell four spots to No. 15 after leading Ohio State for a chunk of the game in Arlington, Texas.
LSU was the big mover for me, shooting up nine spots to No. 6 after its game-winning field goal at Auburn. Auburn fell a couple of spots to No. 9 and will be licking its chops with struggling Arkansas headed in.
West Virginia and Virginia Tech, both idled by the hurricane threat on the East Coast, each slid up a spot to Nos. 7 and 8, respectively. Notre Dame, which won a second consecutive game in underwhelming fashion with a 22-17 victory over Vanderbilt, stayed at No. 10.
UCF, the co-national champions of 2017, remain my top Group of 5 selection at No. 16.
Boise State and Ole Miss fell out of my rankings, while No. 23 Kentucky and No. 24 Boston College jump in for the first time this season.
The SEC leads the way with seven entries on my ballot, with No. 13 Mississippi State and No. 20 Texas A&M joining the aforementioned SEC clubs.
The Pac-12 sets up as an intriguing race. Stanford is my top team from the league at No. 11, followed by No. 12 Washington, No. 21 Colorado and No. 25 Oregon. The Pac-12 has work to do to nab a spot in the four-team playoff.
