Has Celtics captain Paul Pierce played his final game for the Green? Pierce, who'll turn 36 in October, said after the Celtics' season-ending 88-80 playoff loss to the Knicks on Friday that he wanted to play somewhere next season. Asked if it would be in Boston, he said: "That's up to Danny [Ainge, C's president of basketball operations]and them," he said. "I have no idea. . . . I definitely expect to be playing next year." Late Friday night, CSNNE Celtics sideline reporter Greg Dickerson tweeted that he had talked to someone close to Pierce who was certain Pierce's time in Boston was over. Dickerson tweeted: "Talked to some close to Paul, they are certain he's played his last game as a Celtic. Their quote, all good things must come to an end." Pierce, who finished his 15th season with the Celtics after they were eliminated Friday night in Game 6 of their Eastern Conference first-round series with New York, is due $15 million next year if he's brought back to Boston, but only $5 million of that is guaranteed. Pierce could be bought out for $5 million or could be an amnesty candidate, which would give the Celtics some salary cap relief.
