College Football Rankings: 3 Teams That Will Be Out of the Rankings After Week 4

With four Top 25 matchups in action today, it's safe to say there will be lots of changes in the rankings when today's games are over.

The big games start at 3:30 ET, where No. 7 Oklahoma State travels to No. 8 Texas A&M, and No. 11 Florida State waltzes into No. 21 Clemson and their vaunted Death Valley. Later tonight, fans get to see No. 2 LSU pay the No. 16 West Virginia Mountaineers a visit.

It's still early in the season, so many teams will rise and fall quickly in the polls each week.

Here are three teams that won't be ranked after Week 4 is over. 

No. 25 Georgia Tech Yellow Jackets

No. 25 Georgia Tech finally gets a quality opponent in North Carolina this week, and I think North Carolina's defense will be too much for the Yellow Jacket offense.

Georgia Tech head coach Paul Johnson's option scheme has worked unbelievably well this season. They've averaged 59.3 points per game and piled up an unprecedented number of rushing yards. Last week, the Yellow Jackets raced for 768 total yards of offense in a 66-24 romping of Kansas.

North Carolina is 3-0 and coming off of their first ACC-opening win since 2000. They haven't been nearly has prolific as Georgia Tech offensively, but the talent-laden defense has lived up to the hype.

Statistically, Georgia Tech is unreal, but who have they played? An FCS team, a Sun Belt team and Kansas aren't exactly the cream of the crop. There are few teams that rival North Carolina's skill on the defensive line.

Defensive ends Quinton Coples and Donte Paige-Moss are first-round NFL talents, and will wreck havoc in the trenches. Georgia Tech quarterback Tevin Washington hasn't played a team like the Tar Heels yet.

Expect North Carolina to give the Yellow Jackets a lot of trouble today. 

No. 23 USC Trojans

Arizona State slipped up last week against No. 24 Illinois, but look for them to bounce back in a big way at home against No. 23 USC tonight.

Junior quarterback Brock Osweiler looks like a new man this season. He made some mistakes last week, but his growth as a football player has brought this ASU offense to life. Osweiler has completed 66 percent of his passes for 871 yards with six touchdowns and three interceptions in three games.

USC is 3-0, but not in convincing fashion. The offense has lacked sizzle outside of the Matt Barkley-Robert Woods connection in the passing game. Barkley is having his best season yet, but that hasn't translated into consistent scoring for the Trojans.

The Sun Devils' defense is a physical one, and junior linebacker Vontaze Burfict has been terrorizing opposing offensive lines.

ASU can bring the pressure—is USC ready for it? If Minnesota and Utah gave the Trojans problems, what could ASU do to them?

Matt Barkley will have to win this one largely on his own offensively, and that could be a tall order on the road. 

No. 21 Clemson Tigers

No. 21 Clemson welcomes No. 11 Florida State today, but something tells me the Seminoles won't be polite guests.

Clemson is riding high after an emotional victory against then-No. 21 Auburn last week. Quarterback Tajh Boyd has taken over the reins extremely well, tossing for 911 yards and 10 touchdowns with one interception this season. Clemson has a complete offensive attack, with Andre Ellington running the ball behind Boyd.

As for Florida State, they are reeling somewhat following last week's loss to Oklahoma. The bigger loss, however, was the injury to starting quarterback E.J. Manuel that took him out of the game. Manuel, along with starting receivers Kenny Shaw and Bert Reed, are questionable for the game today.

Clemson has one of the best home-field advantages in the country, but historically they are a team that chokes under the pressure of the spotlight. They may get a banged up Florida State offense today, but defensively the Seminoles are healthy, extremely fast and physical.

Even without Manuel at quarterback, the Seminoles match up very well with Clemson's speedy receivers. Tajh Boyd will have to be exceptional for the Tigers to win this game. History tells us that Clemson won't bring their A-game.

In that case, look for Clemson to drop out of the rankings after this week.
