First, he's already missed too many games? Ovechkin, while being incredibly durable through his career, technically missed a season and half within his first 9 years of NHL eligibility. The 2004-05 lockout cost him 82 games and the lockout of 2012-13 cost him almost half a season. Through their first 9 seasons post-draft, Ovechkin played in 601 games total, while Matthews has played in 616 games total.
Second, I think the likelihood that scoring stays up is significantly higher than it going back down without correction. The NHL knows goals = entertainment. They aren't going to allow scoring to stay down for long. The league always wants more goals.
Ovy was healthy the entire time, he had one 10-game suspension and a few suspensions for skipping the all star game. This year was the first injury-lost-time of Ovy's career. Last year was the first year of Matthews career where he didn't miss time for injury.
Yeah when you count a season Ovy wasn't in the league it naturally skews the numbers. The likelihood that Matthews plays at Ovy's level at 39 is also pretty much zero though. Considering Matthews is his his peak now and Ovy is outpacing him in goals this year and they're essentially gathering the same number of points. If 27 Matthews can't pull away from 39 Ovy, it doesn't bode well for his capability to catch him.
PPG in 2024 is like 50 points in 2014, and Ovy never had a down season on that level. Era adjusted Ovy is already 5th all time in points and is already close to 1000 era adjusted goals and is nearly 250 ahead of era-adjusted Gretzky.
Like the criteria for Matthews to catch up requires the following things.
1: He stays completely healthy.
2: Scoring stays in this 80's esque peak and the overall quality of competition doesn't adjust to the 32+ teams that will be in the league.
3: Matthews' game doesn't age whatsoever.
4: He has no more down years.
5: Marner re-signs. Cause let's be honest, he's not going to get 60 playing with Nylander who also likes to shoot and seemingly is trusted more now.
6: The Leafs, or wherever he plays, Need to consistently be a good team with some dedicated passers. If Hull had stayed with Oates, that'd be who Ovy would be chasing instead of Gretzky. Instead, he dropped 20-25 goals a season on average when the Blues traded Oates. Neely got into the HOF because Oates got him 50 in 49. Right now that guy for Matthews is Marner, who is speculatively walking this summer.
I actually believe number 2 will be true, because they are already talking expansion again when there's not even 32 starting goalie-caliber goalies in the world. Lots of records will get broken, just not this one. Because goal scoring consistently for 20 years is something almost no one has done. Gretzky got most of his pre-30, with only 176 goals in his final 8 years. So 718 goals at 30, Matthews is not pacing to hit that with only two more seasons left; he'd need 160 goals per season, slightly less depending on how many he gets this year.
So he's not even close to hitting it through peak numbers, but his GPG is slightly above Ovy at the same age with the benefit of one extra season of play. But Ovy didn't hit it because of what he did from 19-27. He hit it because of what he did from 28-38.
Matthews peak is great, he hit 60+ twice, but never hit 50 in another season. The rest is pace, which benefits him because he went goalless for 5 games at the end of 2022 when he was at 58 goals. And it's a common occurrence where hitting milestones gets in his head and he misses.
Adding pace doesn't mesh with reality, like last year he didn't hit 70 and went pointless and -4 in the final two games. Only to sit out of the final game to rest for the playoffs where he did nothing because he was pushing so hard for regular season success.
I don't mean to say he wouldn't have hit 50, because obviously in some of those years he was pretty close with lots of games left, but I don't think he would have maintained the pace he was scoring at to the conclusion of the season; he would have slumped when getting close bring down his overall numbers.
This argument had more merit last season when it looked like Matthews had unlocked an even higher gear of goal scoring. The reality is he's scoring at the lowest pace of his career now and even the in between point of those two numbers isn't even close to good enough to catch Ovy. Last year's Matthews (60 goals a season) needs to appear for 5-6 years straight to open that conversation as being realistic, as it brings down Matthews to only be 160ish back of Gretzky which lets him average 30ish goals for his 33+ seasons. 10 straight 50 goal seasons would be enough to barely tie Gretzky. When you subtract 3-10 goals a season it becomes very difficult to come close. Like averaging 40 gets him 100 back of Gretzky, let alone what Ovy gets next season. Even 30-40 goals next year puts Ovy so far ahead and increases the pace Matthews' needs to score at by a ton.
One more down season basically ends to conversation completely as he'd need a couple 80 goal seasons or to play til he's 42 at a high level to get back into it.
Also keep in mind there have been four simultaneously rebuilding clubs in Matthews division the last 5 years that are (mostly) now starting to play real hockey. Florida and Tampa don't appear to be falling off either, so there's a lot more tough games that are going to be appearing in Matthews' schedule.
