Despite losing to Ohio State on Sunday, Michigan State remains 22nd in the Associated Press men's basketball Poll.
Florida and Wichita State remain the top two teams.
The Gators won two games last week to improve to 29-2 while the Shockers won all three games they played and captured the Missouri Valley Conference tournament title, upping their record to 34-0. The Gators, who received 50 first-place votes from the 65-member national media panel, open play in the SEC tournament Friday. The Shockers got the other 15 No. 1 votes and are 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 with Louisville jumping from 11th to fifth. The second five this week are Virginia, Duke, San Diego State, Michigan and Kansas 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.
