Yeah i know you said there are different ways to get to 800, just that all your examples of 7 60 goal, 8 50 goal seasons, etc dont really mean much considering it assumes 0 goals for the rest of the seasons. Yes when you say "or equivalent production" thats more accurate but its basically the same as what the other poster is saying by showing that the average number of goals matthews needs is still high but not unreasonable.
In terms of powerplays, yes i think its a given that no matter what matthews will never approach the powerplay time that ovechkin has recieved in his career. I am not suggesting ovechkins incredible powerplay time is due to luck (although you could maybe argue that his first few seasons were when powerplays in the league overall went through the roof). What i am suggesting is that matthews incredibly low power play time thus far is due to being quite unlucky and that this will likely even out over time. Will he get up to ovechkins powerplay times ever during a single season - probably not. But if toronto ever got a few seasons of top powerplay time in the league as washington got during some of ovechkins early years then this will make the road to 800 quite a bit easier.
Yeah I mean we can just look at it from the perspective of averaging 30 goals a season from 2024/25 out and it's still a tall ask. There's a reason that the list only includes 3 players with 800 or more right now. It takes a massive peak like Gretz, insane longevity like Howe or insane consistency like Ovi. Matthews has to hit on one of those to make it. His peak and likely no one's peak will ever hit Gretzky's, it's just to tall of an order. So he is going to have to make up the rest of the ground later on in his career.
We'll never know if Lemieux or Bossy could have gotten there as both were on some pretty insane trajectories but their health just couldn't keep up.
On his current pace Matthews could reasonably be expected to hit 500 goals by his 782nd game, which I think will happen in his 10th season when he will be 28 years old. Which would make him the 5th fastest to do it, surpassing Ovi by 19 games but being behind Hull, Bossy, Lemieux and Gretz.
If he can hit that mark I would consider that a pretty solid marker for him to be on pace but even then that is another 65 goals for each of the next 2 seasons to get there, if he finishes with 70 this year.
I think if he's going to hit it he needs to at least get a few more 60 goal seasons under his belt before hitting age 30 as it seems to be the time when most goal scorers are starting to fade. By 33 many take a big step back and by 35 many more take a pretty big step back. So in order to bank some insurance against age, wear and tear he's gonna need to compile early. My entire thought process behind pushing for more 60+goal seasons early is I don't think he will have the longevity of Howe nor the consistency of Ovi so stockpiling big seasons now and just compiling later on is probably his only real hope of hitting 800+ IMO.
