One cup is special, two is a run, three is a dynasty. Winning a third back-to-back Stanley Cup in 1982 established the New York Islanders as a dynasty in the NHL. A year later the Islanders would become legends in the sport by winning a fourth straight.
Up to that point in the NHL, only one team had won four straight Stanley Cups. The Montreal Canadiens won five straight between 1956 and a1960 under head coach Toe Blake and then won four straight between 1976 and 1979 under head coach Scotty Bowman.
That's legendary status.
