We are three weeks into the college football season and some unexpected things have happened. Alabama is undefeated and ranked No. 1, and teams such as Clemson, Georgia, Ohio State, and Oklahoma also remain without a loss.

Other teams have surprised in both good and bad ways. Here are the highest risers and biggest fallers in the AP College Football Poll since the preseason.

Risers

The Tigers started off the season with a 33-17 win over No. 8 Miami in which they thoroughly outplayed the Hurricanes. A 42-yard field goal by Cole Tracy on Saturday as time expired gave LSU a one-point win on the road against No.

7 Auburn.

  • Oklahoma State (up 14 from No. 29 to No. 15)

Oklahoma State’s defense took down Boise State quarterback Brett Rypien seven times for sacks on Saturday as they dominated the Broncos (ranked 17 at the time) in a 44-21 win. They outscored Missouri State and South Alabama 113-30 in their first two games.

  • Boston College (up 11 from No. 34 to No. 23)

Boston College is off to a 3-0 start, and they are coming off an impressive road victory over Wake Forest by the score of 41-34. Their offense has been hitting all cylinders as they are averaging 52.7 points and 577.3 yards of total offense in their first three outings.

  • BYU (no votes to No. 25)

BYU enters the top 25 for the first time this year despite an earlier loss to Cal.

They defeated Arizona in the opener and pulled off the upset victory at Wisconsin on Saturday. The Badgers were ranked 6 (including one first place vote) entering their meeting with BYU.

Fallers

  • Wisconsin (down 14 from No. 4 to No. 18)

The aforementioned Badgers took a large tumble in the poll after their loss at home to BYU.

According to ESPN, it was their first non-conference home loss since 2003. Rafael Gaglione missed a 42-yard field goal with 41 seconds left which would have tied the game. ESPN also reported that it was the first time this season that a top 10 team lost to an unranked foe.

  • Miami (down 13 from No. 8 to No. 21)

The Hurricanes have moved up one spot after their two recent wins over Savannah State and Toledo, but they are still far off their preseason ranking.

Voters have not been able to forgive them for their opening home loss to LSU where they were never really in the game.

  • Michigan State (down 13 from No. 12 to No. 25)

The Spartans had a tough time taking down Utah State in the opener (won 38-31) and lost to Arizona State in their most recent game on a game-winning field goal as time expired. Michigan State held a 10-point lead in the fourth quarter in that game before squandering it.

  • Florida State (No. 19 to no votes)

Florida State is off to an ugly 1-2 start with both losses coming by 20+ points (24-3 to Virginia Tech and 30-7 on Saturday to Syracuse). Quarterback Deandre Francois is off to a tough start, throwing just three touchdown passes compared to four interceptions.
