A truly legendary number, particularly in hockey.
Three of the best players in the history of the game, Maurice Richard, Gordie Howe, and Bobby Hull wore it and had it retired by their teams.
In football it was worn by Sonny Jurgenson, and in baseball it graced the jerseys of Enos Slaughter, Graig Nettles, Roger Maris, Bill Mazeroski, Minnie Minoso, and of course Ted Williams.
