No. 2 South Florida (6-0)
Last Week: Beat Central Florida 64-12
This Week: at Rutgers (4-2)
Tidbit: South Florida has been labeled as this year’s “Cinderellaâ€Â story. Last year this label was given to Rutgers, who the Bulls face this weekend.

No. 3 Boston College (7-0)
Last Week: Beat Notre Dame 27-14
This Week: Bye

No. 4 Oklahoma (6-1)
Last Week: Beat Missouri 41-31
This Week: at Iowa State (1-6)

No. 5 LSU (6-1)
Last Week: Lost 37-43 (OT) at Kentucky
This Week: Auburn (5-2)

No. 6 South Carolina (6-1)
Last Week: Beat North Carolina 21-15
This Week: Vanderbilt (3-3)
Tidbit: The Gamecocks stay solid with a win over the Tar Heels. A SEC victory over Vandy this weekend would keep them in the hunt for a conference title.

No. 7 Kentucky (6-1)
Last Week: Beat LSU 43-37 (OT)
This Week: Florida (4-2)
Tidbit: Quarterback Andre Woodson showed why he is the front-runner for the Heisman trophy. The road to glory does not get any easier with Florida coming into town.

No. 8 West Virginia (5-1)
Last Week: Bye
This Week: Mississippi State (4-3)
Tidbit: The Mountaineers needed a week off to regain focus. A non-conference victory over the Bulldogs would be a nice momentum swing.

No. 9 Arizona State (7-0)
Last Week: Beat Washington 44-20
This Week: Bye

This Week: at Washington (2-4)

Last Week: Lost 28-31 to Oregon State
This Week: at UCLA (4-2)
Tidbit: The Bears tied with the Bearcats for “fall of the weekâ€Â in the rankings, dropping 10 spots. Cal can right the ship with a win against the Bruins on Saturday.

No. 13 Kansas (6-0)
Last Week: Beat Baylor 58-10
This Week: at Colorado (4-3)
Tidbit: No this isn’t a misprint and these aren’t basketball rankings: Kansas the “jump of the week.â€Â We will see if the Jayhawks are legit in the coming weeks.

No. 14 USC (5-1)
Last Week: Beat Arizona 20-13
This Week: at Notre Dame (1-6)

Last Week: Bye
This Week: at Kentucky (6-1)

No. 16 Missouri (5-1)
Last Week: Lost 31-41 at Oklahoma
This Week: Texas Tech (6-1)
Tidbit: A loss to the Sooners hurt the Tigers, but they played well for all four quarters. They will have a difficult task this weekend stopping the high-octane Red Raider offense.

No. 17 Auburn (5-2)
Last Week: Beat Arkansas 9-7
This Week: at LSU (6-1)
Tidbit: In a game that put most to sleep, the Auburn defense shined brightest. The Tigers need to take advantage of a discouraged LSU squad.

No. 18 Hawaii (7-0)
Last Week: Beat San Jose State
42-35 (OT)
This Week: Bye
Tidbit: The Warriors were able to pull off another close WAC victory last Friday. Colt Brennan might have beefed up his Heisman resume even though he threw four interceptions.

No. 19 Texas (5-2)
Last Week: Beat Iowa State 56-3
This Week: at Baylor (3-4)
Tidbit: The Longhorns broke a four-game conference losing streak, which was their longest in 51 years.

No. 21 Virginia (6-1)
Last Week: Beat Connecticut 17-16
This Week: at Maryland (4-2)

No. 22 Texas Tech (6-1)
Last Week: Beat Texas A&M 35-7
This Week: at Missouri (5-1)
Tidbit: After a week in the honorable mentions, the Red Raiders crack the Top 25. This high-power offense led by quarterback Graham Harrell is primed to make a run in the Big 12.

No. 23 Tennessee (4-2)
Last Week: Beat Mississippi State
33-21
This Week: at Alabama (5-2)

No. 24 Cincinnati (6-1)
Last Week: Lost 24-28
This Week: at Pittsburgh (2-4)
Tidbit: The Bearcats took the “fall of the weekâ€Â along with Cal, dropping 10 spots. Cincinnati can still win the Big East title if they can bounce back.

No. 25 Michigan (5-2)
Last Week: Beat Purdue 48-21
This Week: at Illinois (5-2)
Tidbit: After week one you probably thought you wouldn̢۪t see the Wolverines back, but they nabbed the last spot this week with five consecutive wins.
