North Carolina remains No. 1; Gonzaga 17th

North Carolina (12-0), Connecticut (11-0), Pittsburgh (12-0), Oklahoma (12-0), Duke (10-1) and Wake Forest (11-0) remained unscathed as the top six teams in the ESPN/USA Today Top 25 men's basketball poll released Monday.

The same can't be said for Gonzaga, which nose-dived from seventh to 17th thanks to a pre-Christmas loss to Portland State. The Bulldogs have lost to Arizona, Connecticut and Portland State in the past two weeks.

That opened the door for Texas, Georgetown, UCLA and Notre Dame to all move up a spot to the Nos. 7-10 positions in the balloting of 31 NCAA Division I head coaches.

Also tumbling was Xavier, which fell from 12th to 22nd thanks to a loss to Butler on Dec. 23.

Michigan (9-2) climbed back into the poll at No. 24. It's the first time since Feb. 6, 2006 that Michigan has been in the Top 25.

Last season's NCAA championship game participants cannot be found among the Top 25. Champion Kansas is no longer receiving votes after losing to Arizona, and Memphis -- ranked 24th last week -- fell out of the rankings after a 1-1 week that included a loss to Syracuse.
