According to Woj's twitter, it's a done deal awaiting league approval.
Knicks get Sam Dalembert, Jose Calderon, Shane Larkin and Wayne Ellington as well as the 34th and 51st picks in 2014.
Mavs get Tyson Chandler and Raymond
What's in it for Dallas? Chandler's effective playing days are fading and Calderon is one of the best 3pt shooters in the game. I guess they still regret letting Chandler go a few years ago.
