Tyson Chandler won the NBA championship with the Dallas Mavericks last season.
He went out in the first round with the Knicks this season.

And he isn't happy about it.
"I'm personally very disappointed," Chandler said after the Knicks' 106-94 loss to the Heat on Wednesday. "... It's unacceptable to me. I didn't come here to lose in the first round and I don't plan on doing this in the future."
Chandler, named NBA Defensive Player of the Year last week, played at less than 100 percent the entire series.
He was a game-time decision for Game 1 because of flu-like symptoms. He ended up playing but was severely limited, grabbing just three rebounds in 21 minutes.
Chandler perked up in Game 2 and was feeling close to himself by Game 5. But his presence wasn't enough to cool off LeBron James and the Heat. And that left him pretty hot after Wednesday's loss.
"I'm going to do everything I can to make this team better and challenge my teammates," he said after grabbing 11 rebounds and blocking four shots in 41 minutes.
Chandler wasn't throwing his teammates under the bus for the loss. He also placed blame on his own shoulders for the Knicks' poor playoff performance.
"I tried to find my spot, tried to help my team defensively but ultimately it wasn't enough," Chandler said, "So I too have to look in the mirror and say, 'What can I do for this team next season?'"
He hopes that, after the Knicks' embarrassing losses in the postseason, each one of his teammates commits to improving in the offseason.
"We took a step in the right direction, but we've got a long ways to go," Chandler said. "I'm not satisfied with the first round. I came here to do bigger things, so everybody has to take a step forward this summer. We have to come back focused ... and we’ve got to take a step in the right direction."
