The Villanova Wildcats will start their fourth week as the No. 1 team in The Associated Press Top 25.
The ranked teams stayed the same from the last poll except for the Florida Gators, which replaced fellow Southeastern Conference member South Carolina.
The Wildcats (12-0) received 56 first-place votes from the 65-member national media panel to maintain their big lead over UCLA (13-0), which received three No. 1 votes.
Florida (9-3) returns to the Top 25 after two weeks out of the rankings. The Gators come back in off a 94-71 victory over Arkansas-Little Rock in their first game in the renovated O'Connell Center. They had played their first 11 games on the road or at neutral sites.
South Carolina (9-2) was ranked for four weeks, reaching as high as No. 16. The Gamecocks lost 62-60 last week to instate rival Clemson.
Kansas is ranked for the 150th consecutive poll, a streak that started on Feb. 3, 2009. The second-longest current streak is 86 polls by Arizona. The all-time record is 221 consecutive polls by UCLA from 1966 to '80.
With the start of conference play this week, there are six games featuring two ranked teams.
On Wednesday, No. 2 UCLA is at No. 21 Oregon and No. 6 Louisville hosts No. 12 Virginia. On Friday, No. 21 Oregon hosts No. 22 Southern California.
On Saturday, Villanova puts its No. 1 ranking on the line by visiting No. 10 Creighton. The others are No. 6 Louisville hosting No. 16 Indiana and No. 20 Florida State at No. 12 Virginia.
