Miami Heat President Pat Riley has added another chapter to his rivalry with the Boston Celtics.

After LeBron James complained about calls and Boston Celtics president of basketball operations Danny Ainge chided him for it, Riley lashed back Friday night.

Riley’s response: “Danny Ainge needs to shut the (expletive) up and manage his own team.”

This saga started Wednesday after Miami’s 27-game winning streak ended in Chicago. James told reporters that night that he does not believe some of the hard fouls he takes are “basketball plays.” A day later, Ainge told Boston radio station WEEI that “it’s almost embarrassing that LeBron would complain about officiating.”

Riley was clearly irked, calling Ainge “the biggest whiner going when he was a player.”

According to Ethan J. Skolnick of the Palm Beach Post, “After Donovan relayed Riley’s quotes to the media Friday evening, coach Erik Spoelstra was asked to speak on them. “I love direct GM-to-GM communication,” he said, smiling. “It’s awesome.” Ray Allen, who played for the Celtics the past five seasons, also smiled when the quotes were read to him. “That’s between Danny and Pat,” Allen said. “They obviously have a lot of history.” James does not hold a structured press availability prior to games, but when Riley’s just-released statement was mentioned to him — as he got stretched on the floor and scrolled through Twitter — he referred to it as “awesome.” When told of the statement, a couple of his teammates also heartily approved. Heat players have frequently expressed amusement that representatives of other teams — whether players, coaches or executives — tend to talk so much about them. They are especially amused by the Celtics’ chatter about them, whether it’s coming from Jason Terry or Paul Pierce or whomever; one Heat player referred to it as an “obsession.”
