That imposing figure looking nearly eye-to-eye with Kevin Garnett was Jeff Green. He is a legitimate 6 feet 9 inches, and yesterday he looked as if he had some unfinished business at the Student Activities Center at UCLA.

He was uprooted from Oklahoma City and sent to Boston Thursday in the controversial four-player trade that cost the Celtics popular center Kendrick Perkins. The trade is the talk of the NBA.

How it turns out for the Celtics depends largely on the production of Green, who listened attentively to the orders of coach Doc Rivers and assistant coach Lawrence Frank. He has something to prove. The Thunder felt they were a better team without him, even though he was part of their winning culture.
