The Brooklyn Nets will acquire Paul Pierce and Kevin Garnett from the Boston Celtics in a deal that was still developing as the NBA draft ended, according to a person with knowledge of the details.

The trade can’t be completed until July 10, after next season’s salary cap is set, so pieces were still being discussed early Friday. But the person says the Nets will get the two perennial All-Stars, signaling the breakup of the Celtics’ veteran core…

Yahoo Sports, which first reported the talks, said the Nets would also get veteran Jason Terry from Boston and send Gerald Wallace, Kris Joseph, the expiring deal of Kris Humphries and three future first-round picks to Boston.

On the day they hosted the NBA draft, the Nets were making much bigger noise with the transaction that will send Pierce and Garnett to a new Atlantic Division home.

The Celtics already let Doc Rivers leave after acquiring a draft pick from the Los Angeles Clippers. Ray Allen departed last summer for Miami, and now the other two members of the Big Three that led the Celtics to an NBA title and within a victory of a second will soon be gone as well.
