Who scored the winning goal in the 1980 National Hockey League Stanley Cup Final?

Robert Thore Nystrom (born October 10, 1952) is a Canadian former professional ice hockey right winger. He played for the New York Islanders of the National Hockey League (NHL) from 1972–86. He is best remembered as having scored the winning goal at the 7:11 mark of overtime to give the New York Islanders the 1980 Stanley Cup title. This signaled the first of four straight championships for the club. He was also among the last NHL players to not wear a helmet during a game.

Nystrom was one of the hardest working, if not the most talented, members of the New York Islanders, who were quickly becoming one of the most feared and respected clubs in the NHL. Although Nystrom, who was nicknamed "Thor" by his teammates, had developed into a very skilled and respected fighter with a physical edge to his game, Nystrom took it upon himself to improve his skating ability. He regularly took power skating classes, including training with pioneering instructor Laura Stamm and in time, became a fairly fluid skater with strong hockey instincts.
