Five takeaways from AP Top 25 men's basketball poll

In this week's Associated Press Top 25 men's college basketball poll, released on Monday, a shakeup occurs in the top five. Here are five takeaways from the poll.

Michigan, Illinois move up after signature wins

While the Arizona Wildcats (22-0, 9-0 Big 12) are off to their best start in program history and are one of only two unbeatens remaining alongside Miami (Ohio) (22-0, 10-0 MAC), which moves up one spot to No. 23, a couple Big Ten battles took center stage and shook up the rest of the top five.

Michigan (20-1, 10-1 Big Ten) moves up one spot to No. 2, leapfrogging UConn (21-1, 11-0 Big East), after improving to 5-0 against ranked teams this season with Friday night's 83-71 win over then-No. 7 Michigan State. Prior to that, the Wolverines handed a fifth-ranked Nebraska team its first loss of the season in what turned out to be their only win against a ranked opponent so far to be decided by single digits.

Duke (20-1, 9-0 ACC) remains at No. 4 after staying undefeated in conference play, but Illinois (19-3, 10-1 Big Ten) moves up four spots to No. 5 after its own victory over Nebraska on Sunday. That comes after the Fighting Illini took down then-No. 4 Purdue on Jan. 24.

Nebraska gets humbled after undefeated start

After a 20-0 start to the season — the best in program history — the Cornhuskers (20-2, 9-2 Big Ten) drop four spots to No. 9 after becoming the eighth program in AP poll history to lose its first two games played as a top-five team.

An issue for Nebraska in both losses was its inability to control the boards, getting out-rebounded, 35-23, by Michigan and 40-27 by Illinois. While that poses some concerns, a favorable schedule lies ahead with only one ranked opponent (No. 12 Purdue) remaining.

Kansas, Florida move up after statement wins

The Jayhawks (16-5, 6-2 Big 12) climb three spots to No. 11 after holding off a furious second-half rally from then-No. 13 BYU in Saturday's 90-82 win. In a matchup between two players projected to be at the top of the NBA Draft, Kansas freshman Darryn Peterson outshined BYU freshman AJ Dybantsa in the first half, but a no-show in the second half showed the pros and cons that come with him.

The Gators (16-6, 7-2 SEC) move up two spots to No. 17 after backing up head coach Todd Golden's comments in a 100-77 rout of then-No. 23 Alabama on Sunday. Florida committed its fewest turnovers (two) in any game in the past 30 seasons and dominated in the paint, 72-26.

Arkansas drops six spots following loss to Kentucky

Although the Razorbacks (16-6, 6-3 SEC) started strong after facing a 42-35 halftime deficit to the Wildcats in Kentucky's first game in Fayetteville against former HC John Calipari, they had no answer down the stretch in an 85-77 loss.

Now at No. 21 in the latest rankings, it is back to the drawing board for a team that only shot 3-of-14 from deep and got out-rebounded, 35-26. No. 17 Florida is the only ranked team left on Arkansas' schedule, so perhaps a bounce-back opportunity lies ahead.

Tennessee rejoins rankings at No. 25

The Volunteers (15-6, 5-3 SEC) re-enter the fold on a three-game winning streak. Tennessee has particularly excelled on the glass this season with a Division I-leading plus-15 rebound differential in 11 games this season.
