Kendrick Perkins has been working hard this offseason in turning around his career after a regular season and playoffs in which he often struggled.

Perkins underwent arthroscopic surgery on his right knee last month.

“I've been working, man,” Perkins said. “Been in the gym and basically just working more in the weight room on my explosiveness and touch around the basket, hook shots and stuff like that. I've been shooting a lot of jumpers, making sure I make 300 a night. I'm just trying to prepare.”
