The Longhorns (17-0) moved into the top spot for the first time in school history last week. They stayed there Monday, receiving 57 first-place votes from the 65-member national media panel.
Kentucky (18-0) was No. 1 on eight ballots and remained second in the AP poll. Kansas, Villanova and Syracuse held at third through fifth. The top five spots were unchanged for the second straight week in the USA Today poll as well. The Purdue Boilermakers, previously ranked sixth in both polls, dropped to 13th in the AP and 15th in the USA Today poll after losing to Ohio State and Northwestern last week.
The Jayhawks opened conference play in Lincoln with a win over Nebraska, then dismantled Texas Tech at home.
North Carolina dropped from 12th to 24th in the AP after losing two games last week and three of its last four. The Tar Heels are below 13th for the first time since February 2006. They're hanging around in USA Today voting as well at 23. Baylor crept into the AP poll at 25.
