Boston and its point guard could not agree on an extension, and according to his rep, Rajon is going to be a restricted free agent next summer: “We’re not going to do an extension right now,’ Bill Duffy said. ‘The conversation has been cordial. We’ve been talking the last couple of weeks. There is a difference between the perception of him in their eyes and our eyes. With that being said, the focus is on Rajon to have a fantastic season and concentrate on winning a championship.’ Duffy, who also counts Steve Nash(notes) among his clients, said he is seeking a contract that would pay Rondo like one of the NBA’s top five point guards. The Celtics, Duffy said, ‘feel differently.”’
