Duke is No. 1 in The Associated Press' college basketball poll after dropping from the top spot for one week.
N.C. State is now No. 18.
The Blue Devils, who fell to No. 3 last week, took advantage of losses by Louisville and Indiana to move back to No. 1, their fifth week on top this season. Duke received 39 first-place votes from the 65-member national media panel Monday.
Michigan, which jumped from fifth to second, had 11 No. 1 votes. Kansas, which had seven first-place votes, and Syracuse, which knocked Louisville out of No. 1, tied for third. Syracuse received eight No. 1 votes.
Louisville dropped to fifth and was followed by Arizona, Indiana, Florida, Butler and Gonzaga.
Wichita State, Cincinnati, Mississippi and Miami moved into the rankings this week, replacing San Diego State, Illinois, UCLA and Marquette.
