Ever since the Nets acquired Deron Williams Feb. 23, 2011, from Utah, they've had July 1, 2012, hanging over their heads. That day, of course, is when Williams officially will become an unrestricted free agent and leave the Nets, hoping they've done enough to convince the superstar point guard to re-sign with the team and become the face of the franchise as the team moves to Brooklyn this fall. But with free agency set to kick off at midnight Sunday, Nets general manager Billy King is glad he'll soon know whether or not Williams will be his point guard moving forward.
