James Posey has been to Houston before, and one of the predominant rumors of the day has him pondering the chance to play there again. The Celtics would be happy to re-sign Posey, who was a crucial part of their championship equation, but they don't want to ink him to a long-term deal. Several other teams, including the Rockets, would like to lure him away from Boston and will give him the long-term deal he wants.
