Sam Cassell's contract expires at the end of the season, but there is a chance he could remain with the Celtics as a member of Doc Rivers' coaching staff, according to the Boston Globe.

"Basketball is my passion," Cassell said. "With me, you like to get paid for what you do, but this is my passion. I've been wanting to be a head coach in this league for a while. Just don't be surprised if I leave this game as a player that I might be right up here with Doc on the staff."

"I think he would be a great coach," Rivers said of Cassell. "I just would hate to be in his meetings because he never shuts up. And how would you keep him quiet on the bench? But he has an unbelievable knowledge of basketball. I told him a week ago, 'I hope you're not retiring any time soon, but if you do, I'd love to have you stick around.' And I meant it."
