It took Gonzaga until the regular-season finale to finally taste defeat, and that means Kansas slides back into the top overall spot. Both the Zags and Villanova dropped home games, but each has done enough to remain in the top three for now.
Butler didn't just go into Philly and take down Villanova; the Bulldogs also dropped Xavier in Cincinnati and moved up six spots. Chris Holtmann's team continues to surprise, but it's also difficult to figure out at times.
After steadily climbing in recent weeks, Duke fell again -- after losses to Syracuse and Miami. Two teams that cracked the Power Rankings this week are Minnesota and Iowa State, while USC and Maryland fell out.
1. Kansas Jayhawks
Last week's ranking: 3
The Jayhawks won at Texas and clinched their 13th consecutive outright Big 12 regular-season title.
2. Villanova Wildcats
Last week's ranking: 2
After a shocking loss at home to Butler, the Wildcats rebounded with a victory over Creighton and clinched their fourth consecutive regular-season title.
3. Gonzaga Bulldogs
Last week's ranking: 1
In the Zags' final regular-season game of 2016-17, Mark Few's team lost for the first time, at home to BYU.
4. UCLA Bruins
Last week's ranking: 4
The Bruins beat Arizona in Tucson. It was just the second time the Wildcats have lost at the McKale Center in the past 69 games.
6. North Carolina Tar Heels
Last week's ranking: 9
The Tar Heels won at Pittsburgh and claimed at least a share of the ACC regular-season crown with the victory. It's Roy Williams' second straight league title.
7. Louisville Cardinals
Last week's ranking: 7
The Cardinals split against North Carolina and Syracuse, but free throw shooting is a concern. Rick Pitino's team was 17-of-36 in the two games.
8. Arizona Wildcats
Last week's ranking: 6
The Wildcats' loss at home to UCLA means that Oregon will likely earn the No. 1 seed in the Pac-12 tourney.
10. Kentucky Wildcats
Last week's ranking: 10
Without De'Aaron Fox it was fellow frosh Malik Monk who stepped up and finished with 33 points in a win over Florida. The Cats are a game up on the Gators with two left.
11. Butler Bulldogs
Last week's ranking: 17
Chris Holtmann & Co. had arguably the best week with road wins over Nova and Xavier.
12. Florida State Seminoles
Last week's ranking: 13
The Noles got a rare conference road victory at Clemson. Leonard Hamilton's team entered the game with a 2-5 mark in league play away from Tallahassee.
13. West Virginia Mountaineers
Last week's ranking: 12
Redshirt freshman Lamont West scored 20 points in the first half against Texas, and the Mountaineers swept the Longhorns for the first time since 2013.
14. Duke Blue Devils
Last week's ranking: 11
Grayson Allen sat out the road loss against Miami with an ankle injury, but he played earlier in the week in another road setback against Syracuse.
15. Florida Gators
Last week's ranking: 15
Mike White's team had its nine-game winning streak snapped in Lexington even though Kentucky was without Fox.
16. Notre Dame Fighting Irish
Last week's ranking: 14
Mike Brey and the Irish have won at least 10 ACC games for the past three seasons.
18. Virginia Cavaliers
Last week's ranking: 18
Tony Bennett's team ended a four-game losing streak with a win against NC State, and freshman Kyle Guy went for 19 points -- just the third time since Jan. 1 that Guy got into double figures.
20. SMU Mustangs
Last week's ranking: 22
The Mustangs beat UConn on the road and have won 11 straight overall --- with the last loss coming on Jan. 12 at Cincinnati.
21. Wisconsin Badgers
Last week's ranking: 20
Bronson Koenig became the school's all-time leader for 3s, but that might have been the lone highlight of a week that saw the Badgers lose at Ohio State and on the road to Michigan State.
22. Cincinnati Bearcats
Last week's ranking: 19
With the Bearcats' loss at UCF on Sunday, Mick Cronin's team will likely finish second to SMU in the American.
23. Minnesota Golden Gophers
Last week's ranking: NR
After losing five straight, Richard Pitino's team has reeled off seven consecutive wins to get back into the Top 25.
24. Iowa State Cyclones

Steve Prohm's team has a huge résumé win at Kansas and added another this past weekend after a home victory over Baylor.
