What hurts Lemieux is that he had to compete with Gretzky for a lot of his awards when Lemieux hit his peak Gretzky was still only 27 years old. This plus lemieuxs own injuries prevented him from reaching his full potential.
Three out of Lemieux six art ross trophies Gretzky was a top 3 scorer. With two of Lemieux’s wins coming with Gretzky second in scoring.
Just because Lemieux couldn’t surpass Gretzky ( large part due to injuries) doesn’t mean Howe or Orr would fare any better.
Orr is the only peak that can compete with Gretzky (and I think he has an argument that his peak is better... in fact it's one that I'm coming around to more and more).
For the purposes of any player evaluation, peak is the most important (but not sole) criteria to me. Peak years are the years where that player had *the most* impact. So - and this is for me - peak years need to be both transcendent to be in this group, and sustained (one-two year peaks aren't going to cut it here). Orr had a six year peak that I think can reasonably be said to surpass Gretzky's 8 year peak.
(as an aside - I should note simply counting how many years one player outperformed the other is a dubious endeavor not worth much to me. It lacks all context)
Lemieux's peak doesn't reach the same heights. He might have two or three years which can approach Orr's 6 or Gretzky's 8, but with Lemieux there's always a give and take. The dude took games off. Even before his health problems, he never played a full season. Add on to that, he was a negative asset as a defender. Wayne wasn't much better in this regard, but the difference in offensive production is enough to create separation there, and Orr was flat out a fantastic defender.
Some of the arguments for Orr here have had me scratching my head, because I don't think they are very good, or put forward his best case. Orr has a great case for #1. You just have to weigh peak/prime more (which I think a good ranking *should* do), and you have to address the argument that his 6 year peak is enough. Six straight years of 100 points, six years out of 7 leading the league in +/-, and acknowledge the positional disparity with Hart voting (can you imagine a Dman winning the Art Ross and being a +80 NOT winning the Hart trophy? I mean I know Clarke is a tremendous two-way forward, but if that's not evidence of positional bias against Dmen in Hart voting I don't know what is. AND HE WAS THIRD THAT YEAR!). From 69 to 75, if Orr won the Hart every single one of those years, no one would cry foul.
So this is meandering a bit, but let me try to organize my thoughts. Peak/prime should be weighed more heavily than other criteria (longevity, international, whatever) because that is the period that the player is bringing *the most value* to their team versus the rest of the league. Orr's 6-year peak/prime is at least comparable to Gretzky's 8-year peak/prime (acknowledging that Gretzky has another 7 seasons probably of very high production that constitutes almost a second-prime). The argument for Orr at 1 states that Orr's 6 years added *so much value* as to make up for the lack of longevity, and if you weigh peak/prime as the majority of your ranking, he has a long enough and impressive enough peak to have earned #1.
I think that's a solid argument. Every single player in our top 4 had both stratospheric peaks, but they also won their championships during those peaks. Not a single one won a Cup outside of their period of dominance, so maybe that argument should be counted more.
The counter to that, however, is Howe did almost drag an otherwise mediocre Wings team to some Cups in the 60s, and Gretzky did drag a mediocre Kings team to a Cup Final in 93 (outside of both of their peaks), so while their value wasn't at peak level, they clearly could be the key cog to winning teams. Mario and Orr don't have a similar track, so maybe that's knocks against them relative to Gretzky and Howe.
So one thing - I've tried to stay away from making a qualitative assessment of their relative rankings here. I think I've stated where I come down, but in the interest of discussion I'm trying to put forward what I see as the best argument for Orr (at least the one that's closest to convincing me). Comparatively, Lemieux's inability to stay on the ice strikes me as another incidence that - since we're dealing with marginal differences between legendary players - needs to be discussed.
