I think my favorite line ever was one that really lasted only one season -- but what a season!
The season was 1984-85. The line combination was Wayne Gretzky (C), Jari Kurri (RW), and new Oiler Mike Krushelnyski (LW). When the season started, the Oilers were the new defending Cup champions, but they'd traded a fine player, Ken Linseman, in order to get Krushelnyski from Boston. Sather seemed to have in mind all along that Krushelnyski could play with Gretzky and Kurri. All three forwards were 23 or 24 when the season started.
Chemistry was not a problem. The Oil went undefeated in their first 15 games, during which Gretzky had 15 goals and 43 points and Kurri had 16 goals and 32 points. Krushelnyski was slower off the start, with 7 goals and 13 points during this period, but then he started heating up.
At the annual All-Star Game in Calgary, all three line-members were present, roundly booed by the Saddledome faithful.
At season's end, Gretzky had racked up 73 goals, 135 assists (most all-time until he smashed it the next season), 208 points, and a +98, the highest-ever mark by a forward.
Kurri had missed 7 games to injury, but still recorded a staggering 71 goals, 64 assists, and 135 points, with a +76.
Krushelnyski has amassed 43 goals, 88 points, and a +56 rating in his first year in Edmonton, surpassing expectations.
This single line combined for 187 goals. Think about that for a second. No line in history can match that for a single season.
What's yet more remarkable is that, of these 187 goals, only 36 (19%) were scored with the man-advantage. (Unbelievably, the League's leading goal scorer, Gretzky, scored 8 goals on the power-play and 11 shorthanded... try wrapping your head around that!)
In the playoffs, however, Krushelnyski seemed required to play more of a checking role and he was less often with Gretzky and Kurri (Esa Tikkanen first appeared during the Finals against Philadelphia). While Gretzky and Kurri each had probably their greatest-ever playoffs in '85, Krushelnyski "slumped" to only 5 goals and 13 points in 18 contests. As of the following season, he rarely again appeared with Gretzky and Kurri. He sagged to 16 goals the following season.
