One of the greatest Celtics  in franchise history believes the team’s intensely loyal fan base should trust in Danny Ainge.
Larry Bird , speaking to reporters Monday at the Orlando summer league games, said he understands why his former teammate and current president of basketball operations of the Celtics traded heart-and-soul pieces Paul Pierce  and Kevin Garnett  last week to the Brooklyn Nets.
“Believe me, Danny Ainge knows what he’s doing,” Bird said. “He won a championship. I never doubt Danny Ainge. Danny does a good job. You know, you do get older. You can’t beat Father Time, and I’m sure things will work out.”
Pierce will be 36 next season while Garnett will be 37 when he suits up with Brooklyn. Both, Bird said Monday can be productive with the Nets .
“I think they’ve both been pretty healthy throughout their careers,” Bird said Monday. “They haven’t had the major, major injuries that I had. I think they got plenty left. The way they will be coached and the bench that they have. Yeah — they’ll pick their spots, but when the time comes, they’ll be there.”
Bird, who serves as Ainge’s counterpart with the Pacers, acknowledged it’s disappointing to see Pierce, the second-leading scorer in Celtics franchise history, not be able to do what he did and finish his career playing only for the Celtics.
“I would have loved to see it,” Bird said. “I got a lot of respect for Paul and what he has accomplished. But who says he’s not going to play another four years? It’s a tough situation.”
Pierce, who turns 36 Oct. 13, averaged 18.6 points per game this past season and, with 24,021 points, trails only John Havlicek on Boston’s all-time scoring list.
“[Pierce] is one of the better ones to ever come through there, he really is,” Bird insisted.
