Nominees for the team were selected by a panel consisting of Red Auerbach, Ned Irish, Eddie Gottlieb, Haskell Cohen, Danny Biasone, Lester Harrison, Fred Zollner, Ben Kerner, Fred Schaus, and Bob Feerick. The 25 nominees were voted on by the players who had been named first Team All-NBA up to that point. Bill Russell was the only unanimous selection to the team, and only players who had completed their careers and had been named All-NBA at least once were eligible. In fine condition.
