"It's definitely a privilege to be No. 1. But it's not heartbreaking to me if we drop," Georgia offensive lineman Chris Davis said. "It doesn't matter right now what we're ranked. What matters is our next game and right now, that's Central Michigan. The only time the polls matter is in December. That's when the polls matter."

While the Bulldogs' opened easy, their schedule ultimately should be as difficult as any team's. Georgia's big nonconference test is at No. 15 Arizona State on Sept. 20. The Bulldogs also face six Southeastern Conference rivals that've been ranked in the first two polls.

As for Ohio State, the Buckeyes play at USC on Sept. 13 before getting into the Big Ten schedule.

But of the teams in this week's top 10, USC and Texas are the only ones that don't play an FCS opponent, and the Trojans are the only team that doesn't play a team from a non-BCS conference.

The last team to drop from No. 1 after a victory was USC last season. LSU jumped from No. 2 to No. 1 when it beat Tulane 34-9, the same week the Trojans edged Washington on the road, 27-24.

The last preseason No. 1 team to lose the top spot after winning its opening game was Florida in 2001. The Gators beat Marshall 49-14, but preseason No. 2 Miami opened with a 33-7 victory over Penn State and the Hurricanes jumped to No. 1 with Florida slipping to second.

The next four teams in the new Top 25 stayed the same: No. 4 Oklahoma (two first-place votes), No. 5 Florida (five first-place votes), No. 6 Missouri (one first-place votes), No. 7 LSU (one first-place votes) and No. 8 West Virginia.

No. 9 Auburn and No. 10 Texas each moved up a spot, taking advantage of Clemson's big drop. Clemson, ninth in the preseason, fell out after losing 34-10 to Alabama on Saturday.

Also falling out after losses were Virginia Tech, Pittsburgh and Tennessee.

Moving into the rankings were No. 21 Fresno State, No. 22 Utah, No. 23 UCLA and No. 24 South Carolina.

Alabama moved up 11 spots after its big victory over Clemson.

The second 10 started with No. 11 Wisconsin, followed by Texas Tech, Alabama, Kansas and BYU and Arizona State were tied for 15th. Rivals BYU and Utah are both ranked for the first time since 1996.

South Florida was No. 17, ahead of Oregon, Penn State, and Wake Forest at No. 20.

The final five were all the teams to move into the ranking, except for Illinois, which dropped four spots and tied South Carolina for No. 24.
