Gretzky also scored a ton against goalies basically using street hockey equipment and played in the free wheeling wide open 80s. No need to diminish the goal record. Ovechkin is the greatest goal scorer in NHL history. Nobody considers him to be in the running for best player ever, obviously, but he has proven to be the best goal scorer. There is nothing misleading about the goal record. It is a phenomenal accomplishment.
I think the sacks record is a decent comparison, actually. If Garrett played at a high level into his late thirties, he could maybe challenge, but that is not likely.
