The Montreal Canadians accomplishing something in 1979 which may sound impossible today, which was to win their fourth straight Stanley Cup. Winning two in a row is a huge deal now and has been going back to the Pittsburgh Penguins of the early 1990s, 1991 and 1992 when they won back-to-back cups. The Detroit Red Wings did in the late 1990s in 97 and 98, but no one else had done it since. Because of expansion and free agency with the parity, it is very hard to dominate the NHL for more than one season now.

The Canadians not only won four straight from 1976-79, but five overall in the 1970s. The team of that decade, which is what the Edmonton Oilers were in the NHL in the 1980s. And with the way the NHL is set up today, no other team has dominated an entire decade and been the team of the decade in the NHL since. Because there’s so much parity and so much traveling and so many other things that players have to go through to get through a long 82 game NHL season.
