McDonald, the owner of one of hockey's most iconic mustaches, ended his Hall of Fame career on the highest of highs. His last NHL regular-season goal was the 500th of his career, and his final playoff goal put the Calgary Flames ahead to stay in Game 6 of the Stanley Cup Final on the way to the first championship in their history.
Born in Hanna, Alberta, McDonald was selected by the Toronto Maple Leafs with the No. 4 pick of the 1973 NHL Draft. After scoring 14 and 17 goals in his first two NHL seasons, McDonald broke out in 1975-76 with 37 goals and 93 points. He scored at least 43 goals in each of the next three seasons and scored the series-winning goal in overtime against the New York Islanders in the 1978 NHL Quarterfinals.
