Paul Pierce helped sell Kevin Garnett on Brooklyn

What started off as a casual phone call between good friends has quickly morphed into one of the biggest blockbuster trades of the decade.

Paul Pierce admitted it was he who first reached out to Kevin Garnett about coming to Brooklyn.

Pierce called Garnett in mid-June amidst rumors of a Boston rebuild — around the same time Garnett was denied a chance to play for the L.A. Clippers after David Stern nixed a deal that would’ve sent the 15-time All-Star and Doc Rivers to the Clippers.

“The deal didn’t go through, the Celtics were trading me, Doc was leaving, and so what was left for Kevin?” Pierce told reporters at Barclays Center. “It was one long phone call — probably like two hours.”

“Once Jason Kidd called me, I knew something was happening. Then my agent called me, asking me about Brooklyn and what I think. Once the Nets figured out they wanted to bring both of us in, that’s when I made the call (to Kevin).”
