Wyc Grousbeck took a slight but interesting detour when a discussion with the Herald turned to the Celtics’ roster upheaval.

Asked about the major player changes, the co-owner let it be known he couldn’t speak about the trade with the Brooklyn Nets that has been widely confirmed but is not yet official. Grousbeck then turned to the key move that has been completed — getting a 2015 first-round draft pick from the Clippers for releasing Doc Rivers from his contract.

And while he expressed nothing but appreciation for the job Rivers did with the Celtics, Grousbeck was rather pointed about the process.

“The moves are just rumored,” he said of the aforementioned trade. “I mean, Doc left us, period. Doc left us. No spin will take that away. It was his idea and he left, and we made the best of it.

“We think we’re even with Doc. We think the nine years were nine great years. We would have been happy to continue, but that was not to be. I’m really glad Doc spent nine years here.”

Asked if he was disappointed that there has been some very public debate about how the departure went down, Grousbeck said: “I don’t think anybody thinks there’s two sides to it. I think everybody realizes it’s hard to leave a place where you’ve been nine years, so efforts are made to talk about it different ways, and I don’t have a problem with any of it. I’ve moved on.

“I’ll welcome him back, and I hope we kick the Clippers’ butt. But he’s a champion as far as I’m concerned.”
