Arguably the greatest hockey player to ever live, Bobby Orr is the greatest Bruin ever and the greatest Bruin defenseman of all time.
Orr became the league's highest-paid player as an 18-year-old rookie and changed how the game was played forever.
He is the record-holder for most assists and points in a season for a defenseman and is the only defenseman to lead the league in scoring, which he did twice, according to NHL.com.
From 1968-75, Orr won the Norris Trophy eight times and won the Stanley Cup twice. (In both championships, he scored the winning goal and was named playoff MVP.) Orr also won the Hart Trophy three straight years.
Orr used his speed to skate all over the ice, which was unheard of at that time for defensemen. He remains the most offensively talented defenseman to ever play the game.
Limited by nagging knee injuries, Orr only played 12 years in the NHL. After 10 seasons with Boston, he played two with the Blackhawks before retiring at age 30. He was inducted into the Hockey Hall of Fame at age 31.
