I'd be interested in seeing how many players who played at least 40 games, scored at a 100-point clip, and a point-per-game clip.
Interesting read on TSN if you dig around. Bob McKenzie did a "look back" piece to stories in the news from November 1987. Among the headlines was an obstruction crackdown. I guess there was a lot of hooking and holding in 1987, too.
A lot of reasons why you had the high number of 50-goal, 100-point seasons in 1992-93. Teams played 84 games that year. Obstruction was once again cracked down. Ottawa and Tampa entered the league. San Jose was in their second year. Established teams protected two goalies. These teams struggled to find goalies. I think San Jose set league records for losses and goals against.
Many thought goal scoring would continue to go up in 1993-94. And Florida and Anaheim would be awful. But established teams were only allowed to protect one keeper instead of two, so the newbies got good goalies. And Tampa made a move to get Darren Puppa. The rapid expansion left many teams with only a handful of quality offensive players. That hurt. Elite players got their points. But the days of teams having two or three lines with dangerous offensive players were over.
1995-96 had another obstruction crackdown. But the talent pool hadn't recovered from five expansion teams in three years. Most teams had one dangerous power play unit. A few had two. The elite players put up points. A lot of guys had career years offensively. But the absence of secondary scoring on a lot of teams, (ie: the inability to have a quality second PP unit) is why scoring wasn't higher than 6.3 goals per game. Also, that obstruction crackdown softened as the season went along.
There are a lot of reasons why scoring has dropped. And it's not just an NHL thing. The WHL has had several seasons with scoring under six goals per game. Scoring is down in many leagues, from the NHL to Saskatchewan Midget AAA. I could do an essay on the drop in scoring, but here are a few reasons:
*Expansion. Many teams still can't ice a quality second scoring line, or a credible second PP unit. Players are better skaters, shooters and stickhandlers, but you can't teach a kid instincts or creativity. Get past that first PP unit, and you're set.
And it's not just the NHL that got too big for its britches. Other leagues have, too. It used to be a 16-year-old in the WHL was a sure-fire future NHL star. A few years ago, there were 16-year-olds in the Dub who had zero chance to play in the NHL. Over-dilution forced NHL teams to bring up players before they were ready. That forced major junior teams to bring up players who should have been in junior A or midget. Trickle-down effect.
*Goaltending. Yeah, the equipment is bigger. That helps. But a lot of great goalies were drafted or entered the league in the mid-to-late 80s and early 90s, and they hit their stride in the late 90s. Bigger, quicker goalies who had that mental edge. Roy, Hasek and Brodeur - three of the top 10 ever - were at their peak from 1997 to 2002. The goalies who came along in the late 70s and early 80s were mediocre compared to those before them, and after.
*Development. Junior and midget games used to be scrambly and loosy-goosy. You still see it, but team defence and system play are a much bigger part of the game. A lot of the creative kids have been stiffled. Especially on defence. And I think that shows in the talent pipeline gap for defencemen drafted from 1994 to 2001.
The CHA got the right idea a few years ago when they allowed the two-line pass in minor hockey. I look at the 2008 draft class, which is loaded with quality defencemen. These are kids who would have been 11 or 12 when the two-line pass was permitted. I don't think it's a coincidence. Hopefully these kids develop, and 2008 isn't a blip.
I think hockey would be well-served if kids got back to the old backyard rink. No coaches. No systems. Just work on your game, and find what works for you. And be creative. Too much emphasis on scores at the lower levels.
*Clutch and grab hockey. It wasn't called. And when the league tried a crackdown (1998 playoffs, 2002-03 season) it didn't last. It's seeping back into the game, but it's not as bad as it was from 1997 to 2004.
Two other reasons goal scoring was so high: Gretzky and Lemieux. To have the two best players centres ever enter the league five years apart was a boon. Centre position is the one that drives offences the most. And not only did you have Gretzky and Lemieux, you had a whole host of dynamic, creative pivots who entered the league in the late 70s and early 80s. You also had the first generation of defencemen following the Orr era. Defencemen were encouraged to jump into the rush, and teams were willing to go with an offensive defenceman like a Paul Coffey.
