It took until the second week of the season for a team to break into the Top 25.

North Carolina, Connecticut and Louisville held the top three spots in the Associated Press’ college basketball poll Monday, while Xavier moved in at No. 16 after winning the Puerto Rico Tip-Off.

The Tar Heels (3-0) were again a unanimous selection of the 72-member national media panel.

Connecticut (4-0) beat La Salle and Miami to advance to the championship game of the Paradise Jam, while Louisville (2-0) opened its season by winning its Billy Minardi Classic with victories over Morehead State and South Alabama.

The poll began changing there because of UCLA’s 55-52 loss to Michigan in the semifinals of the 2K Sports Classic.

Pittsburgh (4-0) moved from sixth to fourth, leaping Michigan State (2-0), which remained No. 5. Texas (2-0) moved up one place to sixth, while Duke (6-0), which beat Michigan for the 2K Sports Classic title, jumped from 10th to No. 7.

Notre Dame (2-0) and Gonzaga (2-0) remained eighth and ninth, while Purdue (4-0) moved up one place to close out the Top 10.

Kansas (2-0) moved up to 22nd. The defending champions were No. 24 a week ago.
