Bill Russell is one of the greatest leaders in NBA history. He won multiple NBA titles as a player for the Boston Celtics and also delivered some amazing feats as a head coach of the Celtics. Plenty think about great players and their scoring as to what was the key.

For Russell, the key to his success was his rebounding and defense. And on Feb. 8, 1960, Russell became the first player in the NBA to pull down 50 rebounds in a game — an amazing feat for an amazing basketball player.
