With Paul Pierce and Kevin Garnett in the rearview the Celtics are in a full-on rebuilding stage going into next season. Just one player remains from the 2007 championship team - Rajon Rondo. Depending on who you ask Rondo is either overrated or underrated cocky or confident a punk or a quiet leader. But no matter what you think the kid can play. He's one of the best passers in the game averaging over 11 assists per game in each of the least three seasons for Boston and everybody in the organization - at least publicly - has stood by the point guard. Pierce who spoke with the Boston Globe's Gary Washburn thinks that Rondo is much more mature than people give him credit for. He's confident that Rondo can take the reigns and be the leader of the Celtics going forward. “Without question [he can be the man in Boston]” Pierce said to the Globe. “I’ve already talked to Rajon; Rajon’s mature. People talk about the relationship with Doc [Rivers] and they probably had their best years over the last two years. So I don’t think that was a reason for Doc leaving. I’ve heard that but that wasn’t a reason for Doc not coming back. “Rondo is one of the best players in the league. He’s a guy who can be the face of a franchise. He’s won a championship he’s been an All-Star. There’s a lot of organizations who don’t even have a face of that caliber.
