Tyson Chandler now has entered the United Center as a member of four opposing franchises. What Chandler had never entered his first professional building as until Monday is a champion.

The center, who signed a free-agent contract with the Knicks after backstopping the Mavericks to a title, has a fan on the opposing sideline.

"He's maybe one of the most underrated players in the league," Bulls coach Tom Thibodeau said.

Chandler admitted his first year in the New York microscope has been difficult.
