Jaylen Brown is one of the most critical players on the Boston Celtics, and it’s not just because of his style of play, but also the leadership he brings to the team. Paul Pierce told Heavy Sports’ Steve Bulpett that Brown’s voice is the most important in the locker room, even more so than Jayson Tatum’s. “I’ve always looked at Jaylen as an important voice there,” Pierce said Monday. “When they’re in practice and in the locker room, from what I’m seeing, Jaylen just, personality-wise, is a more vocal person than Jayson. Brown will have the on-floor leadership skills necessary for the new roles while continuing to be the motivating voice in the locker room for the rest of the team.
