It's Monday, there must be a new No. 1.
This time it's Connecticut at the top of The Associated Press' college basketball poll, the fourth straight week with a new No. 1.
The Huskies (20-1) moved up from second to replace Duke (19-2), which fell to fourth after losing on a last-second shot to Wake Forest in its one week on top.
Wake Forest (17-2) was No. 1 two weeks ago, but the Demon Deacons lost to Virginia Tech and fell out. They had replaced Pittsburgh (19-2), which was No. 1 for two weeks before losing to Louisville. North Carolina (19-2) was a unanimous No. 1 in the preseason poll and for the first seven weeks of the season before losing to Boston College.
The five teams which have been No. 1 this season are from two conferences: North Carolina, Wake Forest and Duke of the Atlantic Coast Conference and Pittsburgh and Connecticut of the Big East.
The record for consecutive weeks with a different No. 1 is seven in the 1993-94 season.
This is Connecticut's first appearance at No. 1 since March 2006, and it is the Huskies' 25th week on top, all since 1995.
"I look at it like winning a good in-season tournament like Maui, it's an accomplishment for a minute, a day an hour, a week or whatever, but you want to be there in April," Connecticut coach Jim Calhoun said Monday. "It's still a nice little niche. Out of 343 Division I teams how many have a chance to be No. 1? So it is nice to be there."
The Huskies were challenged immediately and they answered with an impressive 68-51 victory at No. 5 Louisville on Monday night.
"This will be our fourth game in eight days and we have played in Chicago, South Bend and now here," Calhoun said at his team's morning shootaround. "That's life in the Big East."
Connecticut received 64 first-place votes from the 72-member national media panel to easily outdistance Oklahoma (21-1), which moved up from fourth. The Sooners were last ranked No. 2 in the 2002-03 season. The Sooners were No. 1 on five ballots.
Connecticut is also ranked No. 1 in the women's poll, the fifth season in which both programs from that school have been on top.
"I'll keep on saying something is going on in Storrs," Calhoun said with a laugh. "I don't know if anybody is listening, but there's something going on in Storrs."
North Carolina, which received three first-place votes, went from fifth to third and was followed by Duke, Louisville, Pittsburgh, Wake Forest, Marquette, Xavier and Clemson.
Just as the top of the poll keeps changing so does the bottom. Three teams moved in this week: Minnesota returned after a one-week absence. Defending national champion Kansas had been out seven weeks. Utah joined for the first time this season.
Butler moved from 13th to No. 11 and was followed by Purdue, Michigan State, Memphis, UCLA, Texas, Villanova, Gonzaga, Minnesota and Syracuse.
The last five ranked teams were Kansas, Washington, Illinois, Arizona State and Utah State.
Saint Mary's (18-3), which lost two games last week and had Patrick Mills, it best player, break his hand, and Kentucky (16-6) both fell out after being ranked for the one week.
Georgetown (12-8) dropped out from 25th after losing its fifth straight game. The Hoyas were ranked all season, getting as high as No. 9, which was when the losing streak began.
With Georgetown falling out, the Big East is down to six teams in the Top 25. The 16-team league set the record earlier this season with nine teams in the poll in one week. The ACC and Big Ten both have four teams in the rankings.
Kentucky's absence means the Southeastern Conference does not have a team in the poll for the first time since March 7, 1989, when it was still a Top 20. Tennessee, Florida and Kentucky of the SEC were all ranked at some point this season.
Minnesota (18-3), which was ranked for five weeks before dropping out last week, moved in at No. 19 following its dominating 59-36 victory over Illinois.
Kansas (17-4), which had to replace all five starters and a top reserve from the team that won it all last season, moved in at 20th having won six straight games since a loss at Michigan State.
Utah State (21-1) is ranked for the first time since a six-week run in 2003-04. The Aggies have won 16 straight since their only loss to BYU.
