I agree that Lemieux would have scored a 1000 goals if you gave him a healthy career. But if we to play the what if game with Lemieux, then we must also do the same for Gretzky. So let's begin: What if Gretzky had not missed most of the lockout season in 1995? And more importantly, what if he had not suffered the career threatening herniated disc which stemmed from the Gary Suter 1991 Canada Cup hit? His point production plummeted from 163 points to 120 points from one season to the next, and never recovered. He was at a 2+ PPG and dropped to 1.6 (or less) for the rest of his career. His goal scoring plummeted as well. Gone were the 40-50 goal seasons. Gone was the extra gear, which he used to employ every shift. Gone was the crazy lateral movement at top speed. Gone was the ability to traverse in the danger zones without fear of getting hit. Gone was the velocity of his slap shot and what was left of his wrist shot. He became even more a perimeter player after the hit. Then half a season missed of the 1993 season with the herniated disc and half a season missed in 1995 with the lockout. Had it not been for the missed games and lowered goal and point production, Gretzky would have hit 1000+ goals and well over 3000 points (around 3300 regular season points).
As for Gretzky's so called "perfect storm" or 92 goals, his 92 goals (alone) were enough to give him the 2nd most points on his team that season. Kurri scored around 30 goals. Coffey less than that. Messier was not a star either, and Gretzky was playing with the likes of BJ McDonald and Brett Callighan. In other words, not so perfect a storm. Gretzky actually had a better goal scoring season in 1984 when his teammates improved. He scored 87 goals in only 74 games (a better GPG average than his 92 goal season). So Wayne has more 70 goal seasons than Mario (4 vs 2), more 80 goal seasons than Mario (2 vs 1), and the only one with a 90 goal season.... If you want to talk about GPG average, then let's look at Wayne's first 915 games (the same number of games Mario played), and Wayne comes out on top there, too....
