Florida and Wichita State are the top two teams in The Associated Press poll for the third straight week.
The Gators (29-2), who received 50 first-place votes from the 65-member national media panel Monday, open play in the SEC tournament Friday. The Shockers (34-0) got the 15 other No. 1 votes. They won the Missouri Valley Conference tournament Sunday and will be the first team to enter the NCAA tournament without a loss since UNLV in 1991.
Villanova moved from sixth to third, while Arizona dropped one spot to fourth. Louisville jumped from 11th to fifth, followed by Virginia and Duke. San Diego State and Michigan tied for eighth, and Kansas was 10th.
Kentucky, which has lost three of four, dropped out from 25th, the fourth preseason No. 1 to fall out of the poll in the same season.
