Bobby Orr is widely acknowledged as one of the greatest hockey players of all time. He played in the NHL for 12 seasons, starting with 10 with the Boston Bruins followed by two with the Chicago Black Hawks. Orr remains the only defenceman to have won the league scoring title with two Art Ross Trophies. He holds the record for most points and assists in a single season by a defenceman. Orr won a record eight consecutive Norris Trophies as the NHL's best defenceman and three consecutive Hart Trophies as the league's MVP.

In 1966, Orr joined the Boston Bruins, a team that had not won a Stanley Cup since 1941 and had not qualified for the playoffs since 1959. With Orr, the Bruins won the Stanley Cup twice, in 1970 and 1972, and lost in the 1974 Final. In both victories, Orr scored the clinching goal and was named the playoff MVP. In the final achievement of his career, he was the MVP of the 1976 Canada Cup international hockey tournament. Orr was inducted into the Hockey Hall of Fame in 1979 at age 31, the youngest to be inducted at that time.
