Ron Mercer:
On August 15, 2005, prior to the 2005-06 NBA season, Mercer was waived by the Nets to avoid the league's luxury tax as part of the new labor agreement. He has not played in the league since.
In August 2007, Mercer surrendered to police to face a misdemeanor assault charge stemming from an alleged fight at a strip club on April 21. It was claimed Mercer punched a bouncer in the face. On July 17, 2008 Mercer pled guilty and received probation for his role in the fight. The case was handled in front of Criminal Court Judge Steve Dozier with District Attorney Wesley King and Jennifer McMillen disposing of the case.
