Here is the part about Tyson. It is a great article about Cope, his work ethic, his relationship and history with Wallace etc.

Copeland's standout work ethic showed this summer, as he worked tirelessly with Wallace to add strength to his frame and learn more about defensive tactics. Copeland traveled to Los Angeles to train with former Knicks teammate and 2012 Defensive Player of the Year Tyson Chandler for a few days. By summer's end, Copeland had gained about 15 pounds of muscle.

Tyson Chandler's vertical is one of his many physical tools.

"I really got to see why (Chandler) is who he is. That's the best way to put it," Copeland said. "That guy is special and he works extremely, extremely hard. To become a star, you've got to work like that. I have nothing but the most respect for him. I remember leaving there and my legs were so on fire, I was like, 'No wonder he jumps like that.' The stuff that he does in the weight room is pretty intense."

I'm gonna miss Cope. I don't know if he's gonna get any real run in Indy, but I hope he doesn't play well against us. I think Indy grabbed him more to weaken us than to really add a lot to their own team. As for Tyson, I hope we can see him be strong come playoff time and having a deeper team should help with that.

I think Chris Copeland learned a few things from all the Knicks vets last year , he listened to them.

I also believe Indiana signed Copeland just in case Granger re-injures himself, when they had a problem scoring.
