Check out this video from a Penguins' playoff game in 1977 at Toronto. These are, by far, the Penguins' best uniforms ever. Love that blue. The Pens wore these unis only briefly, from 1975-77.
The Penguins won that night, 6-4, but lost the series, two games to one.
This video is chock-full of great highlights. Tremendous give-and-go by Jean Pronovost and Pierre Larouche, the club's first-ever players to score 50 goals. Greg Malone (a/k/a Ryan's dad) nets the game-winner. Channel 11 legend Sam Nover and original Penguins GM Jack Riley do play-by-play and color, respectively.
