SAN FRANCISCO — Golden State Warriors GM Mike Dunleavy said talks about bringing back veteran stalwart Draymond Green and Kristaps Porzingis are ongoing, but sounded optimistic about how the conversations are going heading into free agency next month.“I’ve had conversations with kind of all of our free agents,” Dunleavy said during a Wednesday news conference. “Their representatives. I think we’re in a good place with all of them … as far as Draymond and KP, Draymond has the player option, but we’re in communication with his group. Then same thing with KP. Both guys, I think, we value, we want here, and we see them as a kind of (a) piece of the puzzle next season.”Green, 36, has to decide whether or not to pick up a player option worth almost $28 million for next season. He has said repeatedly throughout the year that he is hoping to return to the Warriors next year, but Dunleavy has been clear that the ball remains in Green’s court. If Green were to decline the option and work out an extension at a lower number, the feeling throughout the league is that he will have a better chance to stay with the Warriors — especially if that lower salary next season helps the Warriors stay out of the luxury tax.When Will Steph Curry retire?Green, as well as veterans Al Horford (who has a player option worth $6 million) and De’Anthony Melton (who has a player option worth close to $3.5 million), have until June 29th to make their decisions, according to SportTrac. Porzingis, who will be 31 in August, was acquired from the Atlanta Hawks just before February’s trade deadline. He is an unrestricted free agent. He made almost $31 million last year, and it remains unclear exactly what the rest of his market will be this summer across the league.
