There's a dramatic photo of Wilt Chamberlain and Bill Russell during a 1967 playoff game at Boston Garden that perfectly captures their historic competition.
The two basketball giants are in sharp focus at the center, alone at the top of their leaps, the top of their games. Dwarfed by sports' greatest rivals, everything else in the photo - the other players, the fans, the hazy old arena - fades into insignificance.
Wilt or Russell? Russell or Wilt?
Fifty years after that photo was shot, 48 years after their last matchup, 18 years after Chamberlain's death, the debate continues about the respective worth of the Hall of Fame centers who dominated the 1960s.
