A little wobbly in recent weeks, USC took the fall on my ballot for this week's Associated Press poll.
The Trojans' 30-27 loss to unbeaten Washington State on Friday night sent those teams in opposite directions, with USC tumbling from fifth to 15th and the Cougars climbing from 22nd to 11th this time around.
My top four remain unchanged with Alabama, Oklahoma, Penn State and Clemson holding their ground with wins. The Tide and Nittany Lions overwhelmed opponents, the Tigers handled a solid Virginia Tech team by 14 and the Sooners enjoyed a bye week before welcoming Iowa State to Norman next weekend.
Washington benefits from Washington State's win, moving into the fifth spot this week with Georgia replacing the Huskies at sixth. The Bulldogs continue a quick rise after blasting Tennessee 41-0 yesterday.
Wisconsin hangs at seventh, with Ohio State, TCU and Michigan each rising one spot to complete my top 10.
After Virginia Tech, which I had 12th a week ago and dropped to 19th this week following the 31-17 loss to Clemson, the only other team in the 13th to 25th positions on last week's ballot to lose was LSU.
Troy spoiled the Tigers' homecoming - then playfully thanked LSU for inviting it to its homecoming game on Twitter.
LSU moves off my ballot this week after sitting in 19th a week ago.
Moving in for now is Georgia Tech, which handled North Carolina on Saturday, but is beginning a string of ACC challenges.
Just on the outside looking in are unbeaten UCF, Oregon and a Maryland team which is 3-1 but was handled by UCF. Oregon and Kansas State are on the radar as well at this point.
Here is my ballot for this week's AP poll:
3. Penn State
8. Ohio State
11. Washington State
13. Miami (Ohio)
14. Oklahoma State
17. South Florida
19. Virginia Tech
21. San Diego State
22. Notre Dame
23. West Virginia
24. North Carolina State
25. Georgia Tech
