The Cougars earned 37 of 62 first-place votes in Monday's poll, extending the program's first stay at No. 1 since the 1980s Phi Slama Jama days for another week. Houston (8-0) beat Norfolk State and Saint Mary's in its first week at the top.
"I don't dwell on it," coach Kelvin Sampson said last week about the No. 1 ranking. "We're not running around here pushing our chest out, thinking we're something we're not."
UConn (9-0) climbed to No. 5, the program's highest ranking since early in the 2011-12 season. Other than the top five, there are three other teams in the AP Top 25 that entered Monday undefeated (No. 11 Auburn, No. 13 Maryland and No. 23 Mississippi State).
North Carolina is only the sixth team to go from preseason No. 1 to unranked since at least the 1961-62 season (most recently Michigan State during the 2019-20 season).
Of that group, the Tar Heels had the swiftest exit from the poll to start the season (four weeks) except for UCLA in 1965-66. The Bruins fell out of the poll after just three weeks back when only 10 teams were ranked.
Ranked No. 18 last week, the Tar Heels (5-4) lost their fourth straight game over the weekend at Virginia Tech while playing without banged-up big man Armando Bacot. They appeared on a single ballot this week from the 62-member panel that votes on the AP Top 25.
"I told them also that I'm not panicked, I'm not any of that," coach Hubert Davis said afterward. "I'm convinced we're going to be a great basketball team by the end of the season."
Last year's Tar Heels were on the bubble to even make the NCAA tournament well into February in Davis' debut season. They went on a final-month tear all the way to the NCAA championship game before falling to Kansas.
THE TOP TIER
Kansas climbed to No. 6, followed by three Southeastern Conference teams in Tennessee, Alabama and Arkansas. For the Volunteers and Crimson Tide, it marked their first appearances inside the top 10 this year. Arizona rounded out the top 10, falling six spots after a loss at Utah.
No. 13 Maryland had the biggest jump of the week, vaulting nine spots after wins against Louisville and Illinois last week in the Terrapins' first year under Kevin Willard. That marks the program's highest ranking since pushing into the top 10 during the 2019-20 season.
Tennessee was next up with a six-spot climb, while No. 11 Auburn rose four spots.
In all, 13 teams climbed from last week.
The Zags, now No. 18, fell four spots to their lowest ranking since checking in at No. 20 on Christmas Day in 2017.
In all, four teams slid from last week.
No. 23 Mississippi State and No. 24 TCU were the new additions to the poll, with the Bulldogs (8-0) earning their first AP Top 25 ranking under first-year coach Chris Jans since January 2019.
The Horned Frogs were ranked 14th and 15th, respectively, in the first two polls before falling out for two weeks.
FAREWELL (FOR NOW)
The SEC led the way with six ranked teams, including No. 16 Kentucky. The Big Ten and Big 12 each had five ranked teams, followed by two each for the Atlantic Coast, Pac-12 and Big East conferences.
The American Athletic, West Coast and Mountain West conferences each had one.
