The most notable game from my memory is St. Louis vs. Los Angeles in the playoffs in 1998. Game 3 I believe. The Kings were down 2-0 in the series but up 3-0 in Game 3. I forget who took an untimely major penalty, but St. Louis got a 5 minute power play and scored 4 goals and won the Game 4-3. I can't think of a time where a 5 minute major was put to use any better.
I remember that game like it was yesterday. Geoff Courtnall of the Blues ran into Jamie Storr(?) (LA's goaltender); Sean O'Donnell of the Kings, I believe, took exception and took a major penalty against Courtnall.
The St. Louis powerplay went to work and basically won that game 4-3. I remember the color guy on ESPN saying something like, "I hate to say it, but Geoff Courtnall is the first star of this hockey game."
As a young hockey fan, I'd never seen anything like it.
My God, according to Hockey Summary Project you're correct!In the infamous 11-0 Hartford win over Edmonton in '84 they scored 4 goals on the same powerplay.
