On a Trip to Boston, Unfolding Memories for Nets Players With the Nets visiting the Celtics on Sunday night, Paul Pierce and Kevin Garnett were expecting their return to Boston to be an emotional one. Pierce, 36, spent 15 seasons with the Celtics. Garnett, 37, joined Pierce in Boston for six seasons, and the two won a championship together in 2008. Last June, both players were traded to the Nets, along with Jason Terry. On Sunday, they will return to TD Garden as visiting players. "I'm sure the emotions will be high," Garnett said late Friday, "and I'll react accordingly." Pierce has been open about his continuing emotional ties to the Celtics organization, which drafted him in 1998, and he was frank early this season about how strange it felt to wear a different uniform. He and Garnett helped lead the Nets to a victory over Boston at Barclays Center in December, however, and they have begun to settle into their roles as the Nets have gone 9-1 this month. Pierce said he looked forward to seeing some familiar faces Sunday at his old workplace, adding that it would be additionally special having Garnett with him. "We shared so many memories, on and off the court - shared our best memories in Boston," Pierce said. We won a championship, and when you talk about the ride we had together and the run, a lot of things go through your head. So it's fun to be able to share it with him. Doc Rivers, who coached Pierce and Garnett during the Celtics" championship run, received a huge ovation when he made his return to Boston with the Los Angeles Clippers, his new team. The same could be expected when Pierce and Garnett, who symbolized the revival of the franchise, return Sunday. Garnett laughed as he rattled off some of his recollections from his time as a Celtics player, saying some were ethereal sensory memories. He said Boston fans had long memories, too. "They never forget their favorites," Garnett said. We were fortunate to be a part of that whole transformation. He added, "Some things are forever, man."
