The Islanders have not won a playoff series since they upset the Penguins in the second round of the 1993 playoffs. That's a story everyone is familiar with. The Islanders have been little more than futile since then.
However, their four-peat to start the 1980s was one of the most miraculous runs in all sports, let alone just New York. The Islanders made the Stanley Cup five years in a row from 1980-84, winning it the first four.
Led by Mike Bossy, Bryan Trottier, Clark Gillies and Ken Morrow, the Isles defeated the Philadelphia Flyers in the 1980 Stanley Cup on an overtime goal at home by Bob Nystrom.
In 1981, they lost only three playoff games en route to repeating.
in 1982, they set a franchise record with 118 points, but were severely tested in the early rounds of the playoffs, going to the maximum five games to defeat the Penguins and six to beat the Rangers. After that, they didn't lose again, sweeping the Quebec Nordiques and then the Vancouver Canucks to win their third in a row.
1983 saw them lose the regular season crown to the Edmonton Oilers and their new superstar, a young kid by the name of Wayne Gretzky. The Islanders exacted their revenge in the finals however, sweeping the young team and winning their fourth Stanley Cup in a row.
Their streak is one of the most impressive in all of sports.
