Tyson Chandler couldn't be at the White House yesterday to be feted along with his former Mavericks teammates for winning last June's NBA championship.

Chandler admitted to being "disappointed'' at the timing, but he had a more important matter at hand: Saving the Knicks form another disastrous result against the Bobcats.

With Carmelo Anthony and Amar'e Stoudemire stinking it up offensively, Chandler came through with his most impactful game as a Knick, willing his team to an important 91-87 revenge victory over Charlotte in which at least the defense showed it is on the right track.
