If the NBA were actually in basketball business — a quaint notion, to be sure — Jeff Green would be a restricted free agent. If a collective bargaining agreement is reached and the lockout ends, he will be free to negotiate with any club he chooses. Including the Celtics [team stats].

But even if Green signs an offer sheet elsewhere, the Celts will still be able to match the deal.

What Green does will be a business decision, but he left no doubt he has some unfinished business here."
