You can change the numbers all you want. I'm just reading what's in the record books. According to the actual record books, Lemieux scored goals at a higher rate than Ovi, regular season, and playoffs.
Scoring in more ways, and being a better one on one player, in my opinion, lends credence to the fact that that player is a better goal scorer. I'm not talking about sheer career numbers. I'm talking about who the best person you've ever seen score goals is. It's the age-old Jordan vs. Lebron debate.
In terms of clutch: Lemieux has way more signature big goals in big situations. 87 Canada Cup, Game 2 goal vs. Minn in SCF in 91, Game 1 winner against the Blackhawks in SCF in 92, etc...Mario Lemieux goals are replayed over and over even now as highlight reels in huge situations and as history for entire countries.
I have no idea about game winning goals or whatever, but Ovi played in an era of 3 on 3 OT and he played a lot more games than Lemieux. But other than that falling on the ground goal in the regular season, I don't recall too many signature Ovi goals. Certainly not to the level of Lemieux. Ovi may very well have more game winners, though, given 3 on 3 and 500 more games. He certainly doesn't have as many winners in big games like SCF, World Cups, or Olympics.
"I'm just reading what's in the record books."
And when you read those record books - you will see Lemieux has no goal scoring record for anything.
Ovechkin: (soon to be) Highest career goal total, most times leading the league in goals, most times leading the league in goals/gp, most powerplay goals, most game winning goals, most OT goals
Ya boy Newsy Lalonde: Highest playoff goal/gp. (unless you want to start talking about goals/gp and how it's harder to maintain a goal/gp rate over a large sample size - in which case you can admit to throwing out the regular season goal/gp comparison between Ovechkin, because you CAN'T compare 915 games of Lemieux who barely played post-age 31 to Ovechkin who has played 50% more games and almost just as much in his 30's as he did in his 20's.
"According to the actual record books, Lemieux scored goals at a higher rate than Ovi, regular season, and playoffs."
And this is exactly your problem. You are correlating that a higher goal/gp = better goal scorer. You are ignoring sample size (Ovi having 50% more games), and those games coming in at older ages where Lemieux inherently would almost guaranteed have scored at a lower rate. And you are also ignoring scoring levels (I'd bring up the whole Crosby/McDavid vs. Recchi and Nicholls thing again but it's clear you refuse to touch that since you know it goes against your opinion.
"Scoring in more ways, and being a better one on one player, in my opinion, lends credence to the fact that that player is a better goal scorer."
I would argue that they 'can' make someone a better scorer. But when the results are that Lemieux being better 1-on-1 and scoring in a more varied type of way didn't actually lead to him being better at scoring goals, then those points are irrelevant to the discussion.
For example, McDavid scores goals in a ton of different ways, and he's also a lot better 1-on-1 than Ovechkin is, but he's nowhere near the goalscorer. The fact of the matter is that Ovechkins shot is so much more elite than Lemieuxs was, that it significantly overcomes a slightly lower level of diversity than Lemieux.
"I'm talking about who the best person you've ever seen score goals is."
And Lemieux may have just been the more talented player overall and that is what is confusing you. Ovechkin has lead the league in goals 9 times. Lemieux nowhere near that. Same dominance when looking at goals/gp. Ovechkin's one-timers might not always be crazy end to end rushes, but it's really just the results that matter (ie. actually scoring goals), and not how impressive those goals are (which I'll get to anyways)
"In terms of clutch: Lemieux has way more signature big goals in big situations. 87 Canada Cup, Game 2 goal vs. Minn in SCF in 91, Game 1 winner against the Blackhawks in SCF in 92, etc...Mario Lemieux goals are replayed over and over even now as highlight reels in huge situations and as history for entire countries."
I'm not denying the Lemieux doesn't have some awesome goals, or that he wasn't clutch. But don't act like Ovechkin doesn't have those moments too. Pretty much everything he did in the Caps cup win was clutch, huge goals in that series. The dueling hat tricks which gets replayed and talked about as one of the best playoff games in NHL history.
"I have no idea about game winning goals or whatever, but Ovi played in an era of 3 on 3 OT and he played a lot more games than Lemieux."
Ovechkin: 135 GWG + 27 OTG in 1,470 GP. 9.18% of Ovi's goals are game winners.
-> Remove 27 OTG/GP/GWG: 108 GWG in 1,443 GP (7.48%)
Lemieux: 74 GWG + 11 OTG in 915 GP. 8.09% of Lemieux's goals are game winners.
-> Remove 11 OTG/GP/GWG: 63 GWG in 904 GP (6.9%)
So give Lemieux all of the advantages possible by largely playing at his peak ages only, remove the OT games from Ovi - and Ovi still has better game winning goal rates (which are probably the easiest of "clutch" metrics to see.
"But other than that falling on the ground goal in the regular season, I don't recall too many signature Ovi goals."
So proof that you haven't watched much hockey in the last 25 years? Ovechkin has likely the most electric goal scoring highlight reel in NHL history.
