WALTHAM — The always media savvy Doc Rivers knows as well as anyone that trade rumors are going to happen in this day and age in the NBA.

But what really gets his goat is when those rumors spring out of nowhere and he’s not even remotely familiar with them. With reports swirling that the Clippers may be interested in Kevin Garnett and with Garnett reportedly saying he’d only waive his “no-trade” clause if Paul Pierce were also dealt out of town, Rivers said Tuesday he’d finally heard and seen enough.

“Really, really I would like to say that sometimes, I like you guys [local media], sometimes some of the stuff that happens is just silly. It really is. When I wake up in the morning and I hear a trade rumor I haven’t heard in my office that’s silly. And that’s what happens.”

Does he address it with the team?

“I don’t even address it,” he said before Tuesday’s practice before the team left for Wednesday night’s game in Toronto. “I really don’t. I rarely do. I don’t 99.9 percent of the time because some of it is so silly.”

The “Inside Track” in the Boston Herald reported Monday that Rivers, Chauncey Billups, Garnett and Pierce had dinner recently as the Clippers were in town to play the Celtics.

“I heard one report, I honestly did, that me, Chauncey, Kevin and Paul had dinner,” Rivers said. “I was like, ‘Well, I wish I would’ve known about it. That would’ve been terrific because I would’ve made them pay and I could’ve had a free dinner.’ It’s just silly what goes on.

“I don’t honestly think it’s [local media]. I think someone can sit behind a computer and write something. The problem is that you guys have to report on it, which you shouldn’t do, but you do and it becomes an issue.”
