Celtics have explored trading Rondo for Stephen Curry

ESPN reports that the Celtics are aggressively shopping Rajon Rondo, and that they tried and send him to Golden State in exchange for Stephen Curry:
Boston is aggressively shopping Rondo, according to sources. The Celtics find Rondo's personality to be too high-maintenance and his clashes with coach Doc Rivers continue. With the Celtics having realized they are no longer title contenders, they don't believe the payoff is worth the headaches Rondo brings, sources say. And they do not want to build around him. In December, the Celtics had discussions with Golden State about a Stephen Curry-for-Rondo deal, and one source says it was Golden State that decided against pulling the trigger. But Curry's recent ankle injuries, which have caused him several problems in his short career, have given the Celtics pause. The potential trade is still being discussed by Boston's braintrust, but they aren't sure they want to go forward with it. It also isn't clear whether the Warriors would be willing to do it. Other players would have to be thrown in to make it work financially.

Well, this rumor comes as a surprise to me, as well. I believe Rondo is a superior player than Curry, but I guess the Celtics are looking for a completely different kind of guard to lead the team. That is, a shooter.

It seems both team are not sure if this could be a good deal for both sides, so this may never become a real deal. Still it makes you wonder what kind of personality Rajon has that it makes it so unbearable for the coaching staff to build around him.
