(NECN: Waltham, Mass.) - The Boston Celtics introduced Rasheed Wallace Thursday.

Wallace is a four-time All-Star, known for his shooting, rebounding and technical fouls.

At his introduction, Wallace addressed his numerous technical fouls. He says his wife has given him different ways to control his emotions.

He says, "Sometimes it works, sometimes it doesn't. For the most part, I don't think my past teammates saw it as a problem."

He admits that he does "go off sometimes", but says overall that he is a pretty good teammate.
