The Power Rankings are one of the few who had Baylor ranked in the preseason, but we won't lie: We didn't see the Bears occupying the top spot at any point in time. But Scott Drew's team is one of the two remaining unbeatens. The Bears have a résumé that can match up with anyone's.
Villanova lost at Butler, and that paved the way for Baylor to slide up a spot into No. 1. It also moved Chris Holtmann and Butler back up into the top 15. Virginia Tech fell the furthest, and Indiana fell out altogether.
The ACC still leads the way with seven teams. The Big East boasts four, and the the Big 12, Pac-12 and Big Ten have three apiece. The SEC and WCC claim a pair each. The American is represented by Cincinnati.
1. Baylor Bears
Last week's ranking: 2
The Bears have never been ranked No. 1 before but should get the nod in this week's AP poll after Miami transfer Manu Lecomte provided the heroics with a game winner to beat Iowa State.
2. Villanova Wildcats
Last week's ranking: 1
Jay Wright and the Wildcats lost at Hinkle Fieldhouse to Butler, snapping the program's 20-game winning streak that began with a six-game run in last season's NCAA tournament. The last loss had come in the Big East tournament championship against Seton Hall.
3. UCLA Bruins
Last week's ranking: 3
4. Kansas Jayhawks
Last week's ranking: 4
Bill Self's team got a controversial victory when Svi Mykhailiuk's game-winning shot against Kansas State counted despite a clear travel on the play.
5. Gonzaga Bulldogs
Last week's ranking: 5
Nigel Williams-Goss went for a career-high 36 points and added 11 assists and six rebounds in a win at San Francisco. The Washington transfer has also improved his perimeter shooting, making 42 percent of his 3s compared with 26 percent two years ago.
6. Kentucky Wildcats
Last week's ranking: 7
Malik Monk has received most of the attention, but fellow frosh De'Aaron Fox has been just as important thanks to his ability to push the pace. His defense is equally important. Fox is averaging 16.3 points, 6.7 assists and 5.1 boards per game.
7. Duke Blue Devils
Last week's ranking: 8
It was an interesting week in Durham. Mike Krzyzewski is taking a leave of absence after back surgery; Grayson Allen returned after a one-game suspension; and Amile Jefferson injured his foot in Saturday's win over BC.
8. Florida State Seminoles
Last week's ranking: 9
FSU and Notre Dame are the lone teams left without a loss in ACC play. However, the Seminoles get Duke at home in Tallahassee on Tuesday.
9. Creighton Bluejays
Last week's ranking: 10
Omaha native Justin Patton continues to gain fans. After Patton went for 25 points and nine boards in a win at St. John's, former NBA great Chris Mullin compared Patton to Marcus Camby.
10. Oregon Ducks
Last week's ranking: 11
11. Butler Bulldogs
Last week's ranking: 19
Butler knocked off Villanova, marking just the second time in school history the Bulldogs have beaten the No. 1 team in the country. The other occasion was in 2012 when they beat Indiana.

The Tar Heels beat NC State by 52 points, North Carolina's largest victory margin ever in an ACC game.

The Cavaliers allowed 88 points in the overtime loss at Pittsburgh, the most they have given up since 93 to North Carolina on Feb. 16, 2013.

After losses at home to Virginia and in South Bend to Notre Dame, the Cardinals avoided going 0-3 in ACC play with a road win against Georgia Tech on Saturday.

Chris Mack said that senior guard Myles Davis, who had been suspended for the first 15 games, has been reinstated -- just in time for Tuesday's matchup at Villanova.
16. West Virginia Mountaineers
Last week's ranking: 12
The Mountaineers rank 299th out of 347 teams in free throw shooting at 64.6 percent. They made 13 of 24 shots from the line in the 77-76 loss at Texas Tech.

22. Saint Mary's Gaels

23. Cincinnati Bearcats
Last week's ranking: NR
Kyle Washington broke out of a scoring slump with 19 points in a win at Houston. Washington, who had eight consecutive double-figure games to open the season, was in double figures just once in the past six contests.
