Rajon Rondo is one of the best point guards in the league, but he apparently has an 'attitude problem' and the Celtics aren't sure of his team building future.

ESPN's Chris Broussard is reporting that the Boston Celtics are currently shopping around Rajon Rondo, but so far have gotten nothing in return.  Now, the Celtics have not confirmed these reports, but it wouldn't be the first time that Rondo's name has been on the trading block.

The Celtics tossed their name into the Chris Paul talk by offering Rajon Rondo, and could possibly get a player like Dwight Howard in exchange for Rondo.  Apparently Rondo has attitude problems, and Boston doesn't think he is the kind of player that they can build a team around.  This trade would come a crucial time as the Celtics 'Big 3', Paul Pierce, Kevin Garnett, Ray Allen, are all getting older and their contracts are expiring.

Doc Rivers however says he is confident that the trade deadline will pass and Rondo will still be in a Celtic uniform.
