David Falk, agent for Jeff Green, has had exploratory contract talks with "12 to 14 teams."

"I know that (the Celtics) want Jeff to come back, from (general manager) Danny (Ainge) to the owners to Doc and to his teammates," Falk said. "He loves Boston. We're waiting to see what happens with KG, what happens with Ray...There are other teams that could be very, very interesting to him around the league that will also have cap room.

"We've picked out three or four teams, of which Boston is one, that he has a high level of interest in talking to. I would say that Boston is the incumbent, but I've learned in this business not to assume things. Nothing is guaranteed."

Falk promises to drive a hard bargain.

"With the possible exception of (Brooklyn point guard) Deron Williams, I think that Jeff will probably be the No. 1 unrestricted free agent on the market," Falk said. "It's not like we have LeBron (James) and (Dwyane) Wade and all these guys floating around.

"I'd be very surprised if Deron Williams winds up anywhere besides Dallas or New Jersey (Brooklyn). So the next guy in the pecking order is Jeff Green.”
