Louisville (16-2), at No. 1 for a week, slips to fifth place and Indiana (16-2) goes from second to eighth. They had company in the loss column, with 12 of last week's Top 25 suffering at least one loss. Illinois, Nevada-Las Vegas and UCLA all drop out of the rankings and San Diego State, which lost twice, plummets from 14th to No. 25. Missouri matches Indiana's six-place fall.
Arizona (16-1) improves one place to sixth and Florida (14-2) is up two to seventh, ahead of Indiana. Butler (16-2) goes from 13th to No. 9 while Gonzaga (17-2), which lost to Butler, drops two places to 10th.
Michigan State (16-3) jumps six spots to 11th but Creighton (17-2) slips two to No. 12. Kansas State (15-2) improves five places to No. 13, with Minnesota (15-3) at 14th and Ohio State (13-4) coming in 15th.
Virginia Commonwealth (16-3) continues moving up and is 16th this week while New Mexico (16-2) is right behind at No. 17. North Carolina State (15-3) is voted 18th with Oregon (16-2), unranked a week ago, in at 19th. Cincinnati (16-3) comes in 20th.
Previously unranked Wichita State (17-2) takes the No. 21 spot, with Missouri (13-4) falling to 22nd. Notre Dame (15-3) sits in 23rd and Mississippi (15-2), the other new entry this week, is No. 24. San Diego State (14-4) completes the Top 25.
