Bobby Orr is widely regarded as the greatest defenseman in hockey history. From the time he joined the Boston Bruins at the age of eighteen, Orr revolutionized the way hockey was played. Prior to that time, defensive players had confined themselves to playing defense. They guarded the approaches to the net and cleared the puck from the defensive zone, leaving the scoring to the front line. Orr played the game differently. He kept possession of the puck rather than simply clearing it, and he frequently crossed the blue line to participate in offensive plays. Orr shattered the scoring records for defensemen, and for two seasons he was the leading scorer in the entire National Hockey League (NHL).
