Is there really no greatest player of all-time?

My favorite all-time great is the Big O, Oscar Robertson. The only NBA player to average a triple-double for an entire season! He doesn't have the rings like Russell, Bird, Magic, Kareem, MJ or Kobe, because he didn't have the personnel they had until Lew Alcindor/Kareem Abdul-Jabbar joined him in Milwaukee. He nevertheless brought his A game every night.
