There's a new No. 1 team in men's basketball thanks to Kansas suffering back-to-back losses.

The Jayhawks fell by double digits to Creighton, 76-63, last Wednesday, and were then toppled by Missouri on Sunday. That opened the door for Tennessee to climb to the top of the Associated Press Top 25 poll.

Auburn would've been the beneficiary of Kansas' upset as the second-ranked team in last week's poll. The Tigers were unable to overcome Cooper Flagg and Duke, though. Flagg had 22 points, 11 rebounds, four assists, three steals and two blocks in an 84-78 victory.

The Blue Devils lost to Kentucky and Kansas by eight combined points this year. Holding home court against Auburn was big toward cementing their credentials as a top team, and it sent them up to No. 4 in the AP poll.

In general, this wasn't a good week to be an AP voter thanks to the bevy of upsets and Top 25 matchups.

Kentucky, Wisconsin and Cincinnati all came up short against unranked opponent last Tuesday. Here's what unfolded on Wednesday night:

• Creighton 76, No. 1 Kansas 63 
• No. 9 Duke 84, No. 2 Auburn 78 
• No. 6 Iowa State 81, No. 5 Marquette 70 
• No. 10 Alabama 94, No. 20 North Carolina 79 
• No. 25 UConn 76, No. 15 Baylor 72 
• Mississippi State 90, No. 18 Pittsburgh 57

Conference defeats for Purdue and Illinois followed that, while Kentucky and Marquette both rebounded against Top 25 foes.

The biggest shock closed out Week 5.

Fans expecting a swift response from Kansas after the Creighton game were sorely disappointed. Missouri jumped on the Jayhawks early and led by 14 at halftime. Having trailed by as many as 24, Kansas made it a two-point game in the second half but couldn't climb out of the hole it dug itself into.

The Tigers' 8-1 start still wasn't enough to capture the voters' attention, though, as they failed to crack the rankings.

Two-time reigning national champion UConn stabilized after going winless in the Maui Invitational. The three straight defeats caused Huskies go nearly go from No. 2 to unranked entirely as they only just held on in 25th.

Beating Baylor gave UConn some positive momentum, and head coach Dan Hurley indicated he may have identified one of the team's issues.

"I think part of the problem has been me," he said. "I've coached these guys frustrated, and I've coached them frustrated for too long. This is a team that's going to be a work in progress, and a team that's going to get better and better. And we're relying on a lot of young players and new players."

The Huskies play Gonzaga at Madison Square Garden on Saturday, which is another opportunity to prove Maui was an aberration.
