Scoring was already really high and rising before Gretzky got to the NHL. It's far more likely that the big bump in scoring was due to the NHL expanding from 17 to 21 teams, with Gretzky himself having a slight effect. With the recent expansion and reduction of goalie equipment (scoring literally jumped the season after it was reduced) it's pretty obvious what the main reasons for the increase in scoring are. McDavid himself is definitely not responsible for that or else scoring this season would be higher than last season with McDavid scoring way more (3.11 last season 3.12 this season)
That would be a silly argument unless you also think 35 year old Crosby, 37 year old Ovechkin and 32 year old Karlsson have improved (of course I mean compared to Karlsson prior to his injury plagued seasons recently). League wide scoring is the biggest indicator of whether a player will put up an all time great point total, by far. Infact no all time great point total has ever been posted in lower scoring seasons just above or around dead puck era levels.
Agree to disagree on that point. For me there's too many other guys who have seen their numbers go up to just brush it off as a coincidence. For example Kucherov was right around the 100 point mark/pace and then suddenly jumped up to 128 points (a total not even McDavid has surpassed....yet) and although he's struggled to play full seasons he has been at a 120 point pace through 40 games the past 2 years as well. Not to mention the large increase in the amount of players hitting 40 goals and or a point per game pace. The timing of this change coincided with the league crackdown on goalie equipment size, which along with a few other factors is what is really driving the change in scoring.
Valid counter-points raised, and I'm not expressly crediting McDavid for increasing league scoring, but the theory that his presence has had an effect is worth exploring. Can transcendent players (maybe too early to declare McDavid one of them, but it's arguable) really tilt the direction of the league in favour of more offense?
Well, the emergence of Bobby Orr - and specifically his unprecedented ability to drive offense from the defenseman position - coincided with a significant increase in league-wide offense. Rapid expansion occurring at the same time muddies the water, but even after the league settled back down and expansion teams matured in the future, the days of d-men not crossing the opposing blueline were gone forever.
Even as scoring increased though, great defensive teams were still the teams that won the Cups (Flyers, Canadiens, Islanders). That changed with Gretzky and the Oilers. Gretzky's incomparable ability to produce offense paved the way for the first offense-first dynasty, and the NHL truly became a run-and-gun offensive league during his prime, and continuing on through Lemieux's prime. The absorption of the WHA is difficult to separate from Gretzky's debut since they occurred simultaneously, and it could very well have been the bigger factor, but the offense-dominated play did continue long after the merger.
The NHL again aggressively expanded in the early 90's, but this time the big scoring bump didn't occur. Or if it did, it was confined to the 1992-93 season. Scoring instead started to rapidly decline after the 1995-96 season. Coincidentally (or not), that was Lemieux's last incredible season. As Gretzky got old and Lemieux retired for the first time, league wide offense diminished.
Outside of those first couple post-lockout years when massive amounts of PPs were being awarded, scoring stayed fairly low up until McDavid emerged, then quickly took off. Was goaltending equipment size being reduced really the main reason for the uptick? Maybe, obviously had some effect, but I think we'd have seen one sudden bump and then a leveling off if that were the case. Instead, offense continues to climb. Covid disruption was obviously a huge variable thrown in there for good measure, so that's another thing to consider.
These might be mainly coincidences that just fit together nicely, but I think there's some validity to the idea that players like Orr, Gretzky, Lemieux, and perhaps now McDavid, simply "raise the boats" around them and their presence increases offense for everyone. Why are teams so much more willing to play riskier run-and-gun hockey right now compared to ten years ago? I personally think there's just a higher than normal level of offensive skill throughout the league today, with McDavid leading the charge, whereas defense and goaltending had the edge for most of the time between Lemieux and McDavid's prime years.
To look at another sport, basketball suddenly evolved into a 3-pointer contest when Steph Curry showed up and was quickly revealed to be the best ever at that particular skill. Everyone else tried to copy and keep up. McDavid is generally agreed upon as the fastest puck-carrier ever. Is everyone else trying to copy and keep up? Looks like some are.
