Good grief, man.
As I already showed, in 1989-90 Gretzky led the NHL in scoring at the end of October, at the end of November, and at the end of December. After 51 games played apiece, he and Lemieux were tied for 1st in scoring. So, yeah, not exactly like Huberdeau and McDavid -- a ridiculous assertion which you should be ashamed of yourself for making.
After his late winter mini-slump that lasted 9 games or so, Wayne had 34 points in 15 games into the latter part of March when he got injured with a pretty severe back injury. If he had maintained that scoring level for the final 8 complete games (which is extremely likely, as it was below his career average), he'd have finished the season with 159 points. Lemieux paced for 167 overall, and he only reaches that 'pace' after a 23 points-in-9 games push before his back seized up, which means his per-game average is likely overstated by projecting him to 167 points. But even so, we're looking at, if both players were healthy, Lemieux scoring around 165-170 points (minus player) and Gretzky 160 (plus player).
Why is it so unGodly hard you to admit that Gretzky and Lemieux were very even in 1989-90 and 1990-91? Does it unsettle your Lemieux-superiority narrative unjustly?
