LeBron James met with Dwyane Wade and Chris Bosh for a light lunch at a boutique hotel near South Beach on Wednesday to discuss their future plans. When the summit concluded, James sped off in a burgundy sports car, and the chase for his services began in earnest. Later in the evening, James showed up for the Beyonce Jay-Z “On the Run” concert – wearing a Miami Heat cap, no less. Meanwhile, the Dallas Mavericks and Houston Rockets made moves to clear up cap space to assist in their efforts to possibly lure him out of Miami. The NBA will look into the future Thursday night when ether Andrew Wiggins or Jabari Parker will be taken first overall in the draft, but the power that James – and to a lesser extent, Carmelo Anthony – wields as a free agent is commanding the present. And it has taken precedence over the proceedings in Brooklyn. The Mavericks and Knicks made the first big trade of the offseason with a deal in which the immediate winner wasn’t one of the teams involved. Dallas re-acquired center Tyson Chandler from New York in a move that eliminated one of the Wizards’ primary suitors for the services of Washington free agent center Marcin Gortat. But for the Mavericks and Knicks, the potential win would come in the long game. The Mavericks clearly have bigger free agent targets in mind after pulling off a deal that also yielded Ray Felton in exchange for Jose Calderon, Samuel Dalembert, Shane Larkin, Wayne Ellington and two second-round picks.
