Doc Rivers wasn’t at the NBA pre-draft combine as workouts commenced yesterday, but nagging media types have been advised to not read anything into that. According to Danny Ainge, there has already been entirely too much “reading into” by Celtics reporters and followers regarding Rivers’ comments and his future as the club’s coach. Ainge rolled his eyes and said again yesterday that this is a non-story. “I don’t even know why I get asked this question,” he said. “Doc is coaching next year. As far as everything I know, he’s going to be our coach. “I haven’t heard anything other than Doc’s coaching next year.” The source for all the public uncertainty is, of course, Rivers, who said after the Game 6 loss to New York when asked if he would be back next season, “I don’t know. I mean, I don’t know that right now. I can’t make that decision now. I’m under contract, and we’ll see. I mean, honestly, I just can’t even think about that right now, so I don’t know.” He has since softened that some, and while most have come to assume Rivers will return, he has yet to verbally shut the door himself. Ainge tried to do so yesterday. “I don’t pay attention to what people say right after a game like that,” he said. “I think guys actually think things a month before the season’s over or when they’re in the heat of the battle. They think what might happen. But after time, rational minds work different.” Rivers’ mind has apparently turned to the Celtics rebuilding needs. “We’re talking about the future,” said Ainge. “We’re talking about next year and the year after. We’re having conversations about what we’re doing next year, what we’re doing in the draft, what we’re doing for our staff. We’re talking about this stuff all the time.”
