This season marked the first time that all three New York City area NHL teams, including the New Jersey Devils made the playoffs in the same season, a feat which has since been repeated twice more: in the 1993–94 and the 2006–07 seasons.
The Edmonton Oilers defeated the Boston Bruins in the Final series, four games to one. For the Oilers, it was their fifth Cup win in seven years, and their only one without Wayne Gretzky (in fact, they defeated Gretzky's Kings in the second round). In game one, Petr Klima scored at 15:13 of the third overtime period to give the Oilers a 3–2 win. As of 2013[update], this game remains the longest in Stanley Cup Finals history (Longest NHL overtime games), edging both Brett Hull's cup-winner in 1999 and Igor Larionov's game-winner in 2002 by less than 30 seconds. In game five at the Boston Garden on May 24, the Oilers won 4–1. Craig Simpson scored the game-winning goal.
