There simply is just no real validity to this claim that an injury is what caused Gretzky's lower goalscoring.
Goal scoring simply is just historically much harder to maintain post-28 years old. Point scoring is too, but it is easier to maintain that elite level of playmaking than goal scoring.
It is evidently clear the following things:
1) Gretzky peaked from 21 to 26 years old from a goal scoring perspective.
2) In the FOUR seasons before either of the 2 major injuries that Gretzky had that almost ended his career, there is a very clear decline in his goal scoring abilities. Despite him remaining the top point producer in the league, he showed a huge decline in his ability to maintain a top goal scorer in the league.
3) Even after the injuries, it is abundantly clear that Gretzky still maintained a very high level of play, but was never a top goal scorer, despite him being a top player.
So to say that he got injured which is the reason that caused him to stop scoring as many goals, then you also have to explain how he could have so many seasons as a top-4 point producer, but not be able to be an elite goal scorer. And if your logic is "he just didn't want to score goals cause he focused on playmaking" - then you're arguing in bad faith and think Gretzky was a moron for not trying to score goals if he was in a better position to score.
