High Quality Content by WIKIPEDIA articles! The 50 Greatest Players in National Basketball Association History (also referred to as NBA`s 50th Anniversary All-Time Team or NBA`s Top 50) were chosen in 1996 to honor the fiftieth anniversary of the founding of the National Basketball Association (NBA). These fifty players were selected through a vote by a panel of media members, former players and coaches, and current and former general managers. In addition, the top ten head coaches and top ten single-season teams in NBA history were selected by media members as part of the celebration. The fifty players had to have played at least a portion of their careers in the NBA and were selected irrespective of position played.
