"I have no idea," Tom Thibodeau muttered, when asked about backup point guard Nate Robinson's post-basket celebrations. "I'm just glad he put the ball in the basket."

But in light of the diminutive scorer's performance in Tuesday night's win over Thibodeau's former employer, the Celtics, even the Bulls head coach couldn't keep up the façade of annoyance.

"He competed hard. He was a catalyst. He made a lot of good things happen for us," Thibodeau went on to say about Robinson, whom was briefly utilized off the ball with rookie point guard Marquis Teague against a Boston small-ball lineup. "His threes were timely. He made some hustle plays for us. He played very well overall."

Robinson scored 18 points, knocked down five of his seven three-point attempts, dished out four assists and only committed one turnover in nearly 22 minutes of action against Boston. More significantly, he electrified the United Center crowd with his energetic play, including one spectacular, but ultimately failed, dunk attempt.

"If he had got that dunk," said teammate Carlos Boozer before taking a long pause and emitting a slow whistle. "That might have been the play of the year."

Robinson himself opined: "I don't want to say I got fouled, because I really don't get those type of calls, but it's basketball, man. Hopefully I'll get a dunk soon. I know all the fans are waiting, so I was really hoping to get that one tonight, but maybe next game."
