I mean - let's imagine a world where Lafleur ends up somewhere between 10-20 in scoring from 83 until say... 87, and then has a few more seasons as a swan song but doesn't really add anything because at that point he's like 38, 39 years old.
How much does that really help his candidacy here? Would we be saying "his 14th place finish in '87 while leading the Nordiques to a second-round exit at the hands of the Habs in 5 games really makes me want to put him ahead of Jagr."
A lot of the longevity arguments don't really control for *meaningful* longevity. Length-of peak, length-of prime, that's what moves the needle for me. Ovi has a meaningfully long prime but a comparatively short peak. Jagr has a pretty long peak, but as far as the length of his prime, it's a bit more uneven (I mean - he has that spike in NY but other than that which of those seasons moves the needle for you? Scoring 70 points in 08?) It makes sense when we're discussing Howe, Bourque, Lidstrom who have those ridiculously extensive time where they were meaningful, elite players at the top of the game. I don't see the same from Jagr most notably, (Ovi is a bit more fuzzy) so I don't really see why it weighs so much more in his favor when compared to Lafleur.
