07:06 AM ET 05.16 | Doc Rivers likely won't be heard from publicly for a bit as he ponders his future, but that hasn't kept Boston's head coach from taking part regularly in the team's plans for next year, according to president of basketball operations Danny Ainge. "I talk to Doc all of the time, and we're talking about our plans for next year," said Ainge, who left [Tuesday] for Chicago to attend the NBA's pre-draft combine. ... Though Ainge regularly talks with Rivers, he said he has not had contact with either Paul Pierce or Kevin Garnett, whose futures figure prominently in his immediate plans. The Celtics have the option to buy out Pierce for $5 million by June 30, or retain him for $15 million for next season.
