1980 Stanley Cup Final

Game one

In game one, Denis Potvin scored twice, including the game-winning goal in overtime, which was the first power-play overtime goal in Stanley Cup Final history.

Game two

After the Islanders drew first blood in game two, Paul Holmgren recorded a hat trick, Bobby Clarke and Bob Dailey each recorded three points for Philadelphia, and the Flyers cruised to an 8–3 victory to tie the series.

Game three

In game three, the Islanders connected on all five of their power plays, with Denis Potvin recording 4 points, and giving the Islanders a 6–2 victory and a 2–1 lead in the series.

Game four

In game four, Clark Gillies recorded three points for New York, and the Islanders defeated the Flyers by a score of 5–2, giving them a commanding 3–1 lead in the series.

Game five

With Philadelphia facing elimination in game five, Brian Propp and Ken Linseman each recorded three points, giving the Flyers a 6–3 victory to send the series to a game six back in Uniondale.

Game six

In game six, Bob Nystrom scored the Cup winner in overtime, his fourth career overtime goal, at the time putting him alone behind Maurice Richard's six on the all-time overtime goal-scoring list. Ken Morrow joined the Islanders after winning the Olympic gold medal with the United States and added the Stanley Cup to cap a remarkable season.

The deciding game six was marred by one of the most infamous blown official calls in NHL playoff history. With the game tied 1–1, the Islanders Butch Goring picked up a drop pass from New York left wing Clark Gillies which had clearly gone back over the Flyers' defensive zone blue line into center ice. Linesman Leon Stickle waved the play as on-side, and Goring threaded a pass to right wing Duane Sutter who beat Philadelphia goalie Pete Peeters for a 2–1 New York lead.^[3] The Flyers argued vehemently to no avail. Everyone on both sides except Goring and Sutter appeared to relax as if play had been blown dead once the puck went over the blue line. Flyers captain Mel Bridgman stated the play changed the momentum of the game at a critical time even though the Flyers scored shortly afterwards to tie the score 2–2. Stickle admitted after the game that he had blown the call. Ultimately, it was the Flyers lack of discipline and the resulting Islander power play goals that were the difference in the series.

Bryan Trottier was awarded the Conn Smythe Trophy as the playoffs MVP, recording 29 points in 21 games.
