AP Polls College Football 2013: Teams That Will Plummet in Rankings

There is going to be a notable shift in the rankings after an eventful week of college football. We had a few top-25 upsets and lackluster performances that will see some teams moving in the wrong direction. 

This shift in the rankings isn't going to happen among teams in the Top Five. However, once we get past that point it is certainly a different story. Check out three teams that must prepare themselves for a slide in the rankings. 

No. 6: LSU

LSU lost a 44-41 thriller on the road against No. 9 Georgia. There is certainly no shame in that, and that in itself is not reason for a huge drop in the polls. However, the problem is the ease with which the Tigers' defense was shredded. 

Georgia put up 494 yards of offense, and that came with both great success on the ground and through the air. 

Given their recent run of dominance led by defense, it is shocking to see this defense get taken apart like it was on Saturday. While LSU flashed a prodigious offense that will keep them relevant all year, it is clear that the Tigers don't have the defense to navigate successfully through their SEC schedule. 

After all, the 44 points Georgia scored is just one point shy of their season high, which came the previous week against the more lightly touted Mean Green of North Texas. 

No. 11: Oklahoma State 

Oklahoma State entered Saturday with a 3-0 record, but the jury was still out on the Cowboys. Other than a 21-3 win over Mississippi State in the opener, the Cowboys hadn't faced an FBS team yet. 

Well, the aforementioned jury has some new info, and I doubt the Cowboys are going to like the verdict. 

West Virginia outperformed the Cowboys en route to a 30-21 victory. 

The Cowboys were on the road, which certainly takes some of the sting out of this loss. Keep in mind, however, West Virginia—which improved to 3-2 with the win—was coming off of 37-0 loss to Maryland the previous week. 

West Virginia has displayed solid stretches of defense this year. So the fact that the Cowboys mustered just 21 points is not terrible. Allowing 30 points to the Mountaineers is another story. The Cowboys are headed towards a massive plunge in the polls. 

No. 22: Notre Dame

Notre Dame is likely enjoying its final moments of being ranked this season. The Irish were easily handled 35-21 by Oklahoma on Saturday and the loss came at home in South Bend.

The Irish allowed 450 yards in this game with the Sooners gaining 212 of those yards on the ground. This is a terrible sign for Notre Dame.

The Irish defense was looking like a shell of last year's version heading into this game and their putrid performance confirms that dubious suspicion.

This is especially problematic for Notre Dame since it's clear the offense will not be bailing them out. The Irish have a serious quarterback issue. Tommy Rees was just 9-of-24 for 104 yards with two touchdowns and three interceptions. 

That isn't going to cut it.

Notre Dame's remaining schedule is not daunting. No. 5 Stanford is their only ranked opponent remaining. Still, they play Arizona State and USC in their next two games, and I'm not going to pick them to win either of those.
