Im okay with people arguing against the use of advanced stats. But what you just posted is false and shows a general lack of understanding of adjusted stats. You’re not comparing the outliers of different eras to each other. You’re normalizing the average player of the different eras and comparing the outliers to that average player. So you’re comparing their levels of dominance over their own eras. Which is the logical way to do it.
And you’re listing all these variables that you don’t think are being accounted for. But they are. That’s the whole point of using league scoring average. All of those variables are accounted for in that simple statistic. Rules, equipment, styles, etc. all feed into how many goals were scored on average.
You can argue the exact formula being used, but whichever reasonable formula you use is gonna yield similar results. It’s not so much using the exact adjusted total goals to say player X is now superior to player Y. But it’s a helpful tool to see that player X is in the same tier as player Y despite lower raw totals earned in a less forgiving era.
The point is that if you're trying to evaluate who
the greatest is, and then you normalize what the league
should be, it's in effect implying that the legends of today must be fundamentally equal to the legends of yesteryear. That's is the implicit flaw in this approach.
There isn't a mathematical formula that can account for the kinds of variables that would change by moving a person across eras (not just of sport, but of culture and lifestyle and everything else that goes along with competing at the highest level, in any era). All you can do is look at what they did in the time they played, and extrapolate arguments based on what was witnessed. I think the underlying problem is that people, especially younger people who never witnessed those performances with their own eyes, want to have the ease and confidence in being able to look at a number and say, "This one's better."
Unfortunately, when you're talking about time travel and doing all of these other ridiculous experiments within the imagination, there are a lot of dynamic variables that aren't solved for by weighting goals as 0.833 or 1.37, or whatever it is. If you believe that you can simply "know" what would have happened by toying with this number and that number, I don't know what to tell you, other than that statistics are compelling by nature and
can be made to say anything.
This is why I try to parse through and put together arguments for individual merits, in what way I define their legacy of greatness. Ovechkin is undeniably a great player, and he may have the greatest slapshot I've ever seen. He also takes an ungodly number of shots which I factor in when I evaluate what "greatest goalscorer" means, but, while you can disagree on whether that should be something I consider, where he slots in terms of the hierarchy of hockey greatness I've witnessed in my life... he won't be forgotten by me, but he also hasn't done enough to leapfrog the legends I've seen.
The fundamental problem here is people who want to believe that there's some algorithm that will let you resolve once and for all debates that span time. There isn't. There's always going to be room for discussion but I hope it will get to a more nuanced and interesting point than thumping on a spreadsheet that someone keeps tinkering with.
The fact that Ovechkin has the opportunity to author his legend by staying healthy and continuing to unload on the net is a testament to what a generational marvel he's been to watch, but until his career is finished, I'm going to hold off on where he belongs on the mantle of all-time greats.
