You are missing something here though as back in Howe's day teams didn't run up the score like they did in Mario's time and also Power plays and thus PP scoring was much less than during Mario's heyday.
52-53 when Howe won the Art Ross by a score of 96-61 (Lindsay was his team mate) they had several high scoring games against Boston and the Black Hawks but also had 9 games with 1 GF and 8 games shutout and that says something about the playing style and dynamic of the league back then.
The 92-93 season had an extra ordinary number of career years for guys and scoring for everyone was way up so you need to account for that somewhat right?

44 guys had 85+ points that year perhaps do some research?
