Bobby Orr (2)

One of the highest scoring NHL defensemen ever to play the game and generally considered one of the greatest ever, at any position. He played in the NHL for The Boston Bruins (1966-76) and The Chicago Black Hawks (1976-77, 1978-79). Retired prematurely in the early 70s due to chronic knee injuries and moved on to become a highly touted player agent in the league he once played in.
