There wasn't a ton of movement at the top of the college football rankings this week, as every Top Five team came away victorious or had a bye week. But with four ranked teams suffering upsets, there is no question that this week's AP Top 25 poll has taken on a different look.

*Full Bleacher Report poll can be found here.

Despite having a bye week, the Alabama Crimson Tide deservedly remain at No. 1. They are the defending champions and are coming off an impressive victory over Virginia Tech. Aside from 'Bama, the other top-five teams won comfortably as well.

Oregon destroyed Virginia to remain at No. 2, Ohio State beat San Diego State handily, Clemson housed South Carolina State and Stanford took care of a tough San Jose State team that gave the Cardinal some trouble last year.

Despite the Buckeyes' easy win over an FBS team, the Tigers overtook them in the new poll after demolishing an FCS squad. Clemson was nipping at Ohio State's heels in last week's poll anyway, and the injury to Ohio State quarterback Braxton Miller may have the voters down on the Buckeyes to a certain extent.

South Carolina wasn't quite so lucky, as the Gamecocks were defeated 41-30 by the Georgia Bulldogs. While Georgia had been ranked ahead of South Carolina to start the season, the Dawgs were knocked down to No. 11 due to a Week 1 loss to Clemson. UGA proved they're still a force to be reckoned with, though, as quarterback Aaron Murray put on a show against a tough Gamecocks defense.

The middle of the AP Top 25 saw the most movement. Florida, Notre Dame and Texas all lost their Week 2 games as well as valuable positioning in the polls.

Florida was previously ranked No. 12, but the Gators took a big hit after being upset by the Miami Hurricanes. Florida's defense actually played very well, but quarterback Jeff Driskel and Co. turned the ball over five times, allowing Miami to win 21-16.

There was talk about the Hurricanes potentially being ranked following their Week 1 win, but they fell just short despite receiving 127 votes. Miami couldn't be held out of the Top 25 any longer after upsetting Florida, though, as the Hurricanes ended a long drought outside the rankings.

CBS Sports provided a statement from Miami (FL) head coach Al Golden following the team's victory:

"It's been such a hard road," Golden said. "We've just been battling this thing and obviously they're one of the teams they've been battling during this thing. I think you guys can figure that out. It was just a very cathartic moment. It was a great moment for our guys, all those guys that not only chose the University of Miami during this but stood there and fought."

Notre Dame also came up short, which means that the Irish will not accomplish back-to-back undefeated regular seasons. Notre Dame's loss is a bit more forgivable than Florida's, though, as the Irish dropped a 41-30 decision to the Michigan Wolverines at "The Big House." That victory bolstered Michigan's ranking, but it certainly put the Irish in a difficult position.

Texas also suffered its first loss of the season, which dropped the Longhorns from the rankings. BYU absolutely destroyed Texas on the ground, as the Cougars ran for 550 yards en route to a surprising 40-21 win at home.

Perhaps the worst Top 25 loss came courtesy of USC, as the Trojans were upended by the Washington State Cougars thanks to a late field goal. The Trojans haven't really impressed the pollsters, as evidenced by their No. 25 ranking heading into the game, but they'll be hard-pressed to get back into the Top 25 at any point this season after losing to the Pac-12's perennial doormat.

While Week 2 certainly answered some questions, the men will truly separate themselves from the boys in Week 3. The marquee matchup will feature Alabama vs. Texas A&M in a game with big-time national-title implications, and many other ranked teams have some tricky opponents on tap as well.

The college football fun has just begun, and the games are going to become even more meaningful as the season progresses. With that in mind, the AP Top 25 Poll is sure to undergo some significant transformations in the coming weeks.
