Just an absolute clinic put on by 99. 39 years ago, G put up a 5-spot to give him 50 goals in just 39 games en route to a still-record 92 goal season.
I don't think 50 in 39 or 92 will ever be beaten only because goalies are so much better across the board these days. Guys are skilled enough to do it---but the goalies are collectively too good. Having said that, I'd love to see it.
As would Gretzky.
The only guy to come close?
Cam Neely scored 50 in just 44 games during the '93-'94 season. And he did it on one good leg. It was his 3rd and final 50-goal season. He also won the Masterton Trophy in 1994.
