AP College Football Poll: 3 of the Biggest Surprises in the Top 25

The college football season is still relatively young, and for now, the polls don't mean very much. After all, most of the big conference games have yet to be played.

Still, that doesn't mean each week—whether early or late—doesn't provide a few surprises when the rankings are released.

Here is a look at three changes in the most recent AP poll that might deserve a second look.

LSU Moves Past Oklahoma at No. 1

Both the Sooners and Tigers (and Alabama for that matter) have impressive resumes, and at this semi-early stage of the college football season, they appear to be the nation's three best teams.

But after seeing Oklahoma atop the AP poll through the first four weeks of the season, LSU supplanted the Sooners at No. 1 after Week 5.

And while that might have been a surprise, it is difficult to say it isn't fair.

After all, it might be accurate to say the Tigers have played the nation's toughest schedule so far, and with blowout victories against Oregon (at a neutral site) and at West Virginia, why shouldn't LSU be on top?

South Florida Is Ranked Seven Spots Ahead of Florida State

Having opened 4-0, South Florida is now 16th in the AP poll. Meanwhile, in-state powerhouse Florida State (2-2) is 23rd, having lost in back-to-back weeks to ranked opponents Oklahoma and Clemson.

When pressed, you probably won't find many voters who believe the Bulls, whose biggest win came in the opener at Notre Dame, are better than the Seminoles. 

Still, they remain unbeaten and gradually inch upwards, while FSU must now work to regroup.

Clemson Continues to Rise

Two weeks ago, Clemson didn't receive a single vote in the AP top 25.

Now, the Tigers are 13th.

That will happen when you follow up a victory against defending BCS national champion Auburn with a defeat of powerful Florida State.

Suddenly, a season that looked like it might primarily be used to integrate a quality freshman class into the rigors of college football is turning into one that could have an ACC championship look for Clemson (4-0).
