BOSTON—At a press conference last week discussing his suspension for bumping a referee, Celtics guard Rajon Rondo blamed his conduct on having "too many role models and people to look up to" on the team to get a coherent idea of how he should act. "I had three different aging superstars, plus a coach who once played and has sons my age, giving me four different lectures about the bump," said Rondo, adding that he once tried to carry himself like Kevin Garnett, only to have all his other father figures tell him that is not how a professional should act. "I do act out from time to time, but I have no young teammates to compare my conduct to. Sometimes I wonder if these guys sort of need me to cause problems, because without me, they would have nobody to mentor." Rondo said he has talked to Celtics general manager Danny Ainge about adding a young player to the roster so he can have somebody his own age to play with, but Ainge just told him a story about asking the same thing of the Celtics GM when he was a player.
