Once again, we are all being reminded that preseason polls mean nothing in college football, as several teams have risen as others have plummeted.
In comparing the preseason AP poll to this week's AP poll, it's a completely different animal.
We've seen programs like Michigan, Michigan State, Arkansas, Wisconsin, Virginia Tech and Oklahoma State all slide just five weeks into the 2012-2013 campaign.
Here's a look at the biggest risers so far this season heading into Week 6.
3. Mississippi State (4-0)
In yet another example of preseason polls meaning nothing, Mississippi State received one measly point in the AP poll before the season.
Four games in, the Bulldogs have gone 4-0 while allowing just 13.3 points per game.
Sure, this has come against unranked opponents, but that doesn't change the fact that the pass defense has looked very good (5.7 yards per attempt, two passing touchdowns, nine interceptions).
Beyond that, the offense has been rolling along, averaging 36.0 points per game.
Mississippi State visits Kentucky on Saturday.
2. Rutgers (4-0)
Rutgers wasn't even on the bubble of the AP poll before the season, but the Scarlet Knights have gone 4-0 to start the 2012 campaign, including a 35-26 victory over Arkansas two weeks ago.
The Rutgers defense is allowing 12.8 points per game this season (10th in the nation) and has allowed four passing touchdowns to six interceptions.
Beyond that, sophomore quarterback Gary Nova is having a breakout season, averaging 7.8 yards per attempt with nine touchdowns to two interceptions. He went 25-of-35 for 397 yards and five touchdowns against the Razorbacks.
Remember, Nova was ranked 11th among quarterback recruits last year by Rivals.com.
Rutgers plays Connecticut next.
1. Oregon State (3-0)
After going 3-9 last season and 5-7 in 2010, Oregon State has come out of nowhere to shock the nation in 2012.
The Beavers have already beaten Wisconsin and UCLA this season, guided by a passing attack averaging 8.6 yards per attempt (17th in the nation), with six touchdowns to one interception.
Sophomore quarterback Sean Mannion has been worlds better since a rough freshman campaign. His passing yardage and passing touchdowns have gone up in each successive game.
Washington State is up next for the Beavers.
