1975 Quarter-Finals: After defeating the Rangers on JP Parise's overtime goal, the Isles drop the first three games to Pittsburgh. In fact, the Penguins led 3-0 in each game, and never trailed in any of them. However, the Isles turned the tables, and completed the dramatic comeback in seven games. Ed Westfall's third period tally was the only goal of Game 7 as the Islanders, who never trailed in games 4-7, became the first team since the 1942 Maple Leafs to erase a 3-0 deficit to win a best-of-7 series.
1993 Divisional Finals: The two-time champion Penguins (who, with help of overtime, had a 17-game win streak in the regular season) were heavy favorites, particularly with the Islanders missing Pierre Turgeon following Dale Hunter's hit from behind. Trailing 1-0 in game 1, the Isles rallied for a 3-2 victory, but Penguins wins in game 2 and 3 gave Pittsburgh the series lead. Game 4 at the Coliseum was a classic 6-5 Islander win, highlighted by two Tom Fitzgerald shorthanded goals (on a penalty that should have been assessed to him). The Champs won 6-3 in game 5, but the Isles forced the series to game 7 with a 7-5 victory in game 6 (Steve Thomas had 4 points). Game 7 was played in Pittsburgh on May 14th and the underdog Isles led 3-1 late in the third period (sound familiar?). The Penguins rallied to cause overtime, but 5:16 into the session David Volek scored to dethrone the Penguins. The potential dynasty was derailed; had the Penguins won that game history might have remembered the Penguins as, well, the 1980-83 New York Islanders.
