Kareem Abdul Jabbar Hakeem Olajuwon. I think the ‘big ball’ lineup would come out on top, though like many scenarios in life, it depends. Kareem played in the 70's/80's, eras filled with great, strong, defensive, hard, athletic, muscular, tall centers, hard players and hard rules, unlike.
But kareem is one of the greatest players in the history of the game. Would this be an official game, with all rules enforced? I would give the edge to kareem.
