The updated poll was released Monday.
Duke (12-0) again reaps 30 of the 31 first-place votes and was second on the other. Michigan (13-0) is ranked second for a third consecutive week, getting the other first-place vote, 29 seconds and one third.
A relatively light schedule during Christmas week brought losses by Cincinnati and UNLV, resulting in seven-spot falls in the poll. Cincinnati (12-1) lost to New Mexico and drops to 15th while UNLV (11-2) was beaten by North Carolina and slips to 24th.
Another notable loss last week was Kentucky falling to Louisville. It was the fourth loss of the year for the NCAA defending champion Wildcats and the coaches drop them from the Top 25 this week.
Last week Arizona and Louisville were tied for third but Arizona (12-0) is ahead now and ranked third, with Louisville (12-1) in fourth. Indiana (12-1) remains fifth followed by No. 6 Kansas (11-1) and seventh-ranked Syracuse (11-1).
Ohio State (10-2) and Florida (9-2) are both up two places to eighth and ninth, respectively, while Gonzaga (12-1) moves from 13th to No. 10.
Creighton (12-1) moves up to 11th but Missouri (10-2) slips from ninth to 12th. Big Ten foes Minnesota (12-1) and Illinois (13-1) both improve one place to 13th and 14th, respectively, with Cincinnati at No. 15.
Georgetown (10-1) keeps moving up and is now 16th. San Diego State (11-2) falls one spot to 17th and is followed by, in order, Michigan State (11-2), Notre Dame (12-1) and Butler (10-2). Oklahoma State (10-1) comes in at No. 21 and Pittsburgh (12-1) takes the 22nd spot. New Mexico (13-1) re-enters the rankings ahead of UNLV (11-2) and North Carolina State (10-2) is again No. 25.
