Celtics working on transition offense - The Boston Globe
Garnett, a 10-time All-Star, has said Mitchell taught him how to be a professional after entering the NBA out of high school.

Not long after the Celtics acquired Garnett in a blockbuster trade in July, he called Mitchell to tell him how ecstatic he was to be going to Boston. Garnett reiterated those feelings to Mitchell in Italy.

“[Garnett] loves being in Boston, loves his teammates,” said Mitchell, the winner of this year’s Red Auerbach Trophy as Coach of the Year. “He said if he knew the NBA was like this, he would have wanted to be traded a long time ago . . .

“I just think everybody does things a little different and he just enjoys it. When you’ve been in one place your whole career, you forget how other people do things and he’s never seen how other organizations work. I think he’s very impressed with the way Boston treats their players and how they do things.”
