On this day, April 4th in 1970, Bruins’ Hall-of-Fame blue-liner Bobby Orr became the first defenseman in NHL history to win a scoring title. No. 4 took home the Art Ross Trophy for the 1969-70 NHL season with his 120 points. The greatest hockey player of all time also won the Norris Trophy — second of eight — and the Hart Memorial Trophy — first of three — at the end of the season.

To top that historical season all off, Orr scored that famous game-winning goal against the St. Louis Blues to take Lord Stanley’s Cup back to Boston for the first time since 1941.
