They’re getting the band back together in Dallas. Or, at least, one significant part of the band.

Tyson Chandler, who left Dallas for New York as a free agent in 2011, is heading to the Mavericks in a trade that will send guards Jose Calderon, Shane Larkin and Wayne Ellington to the Knicks, along with big man Sam Dalembert and second-round draft picks.

Mavericks forward Dirk Nowitzki, in town for Steve Nash’s Showdown in Chinatown charity soccer event, said that bringing Chandler back to Dallas — where he helped the Mavs to the 2011 NBA championship — would be a boon for the team.

“He helped me get a championship, so we had great chemistry together,” Nowitzki said. “So if it is true, I will be thrilled.”

Nowitzki himself is a free agent, and though he is 36 years old, he once again led his team in scoring, averaging 21.7 points and 6.2 rebounds. He said he still intends to play two or three more years, but fret not, Mavs fans — Nowitzki has no intention of leaving Dallas, and made that clear on Wednesday.
