The Celtics would love to be in the mix for Tyson Chandler, who gave Dallas a defensive and rebounding presence inside. Chandler earned $12.6 million in the final year of his contract and bringing him back will be more difficult than Barea. “Right when [Chandler] got there, we kind of viewed him as our quote, unquote, Kevin Garnett,’’ Cuban said. “The guy that was going to be vocal, that was going to hold people accountable. I remember having conversations with him, it’s OK to yell. This team has enough camaraderie and trust that you can do those types of things. He kept on bringing it.’’ Boston Globe
