Well, the Boston Celtics offseason is officially underway. Brad Stevens traded Kemba Walker to the Oklahoma City Thunder for Al Horford to kick-off his tenure as President of Basketball Operations.
In addition to Horford, the Celtics received seven-foot-two center Moses Brown in the deal. Whether Stevens chooses to trade Robert Williams in a big-time move or Tristan Thompson in a lesser deal, one of these centers is likely to be on the move.
