What a terrible take lol. Scoring overall was way higher in the 80's.
For example, Ovechkin won 5 rockets where he scored between 49 and 53 goals (full seasons) between 2013/2014 and 2018/2019. He had 5 of the 6 highest goal scoring seasons in that spa, and 80% of the 5x 50-goal seasons in that span (6 years)
80/81: 8x 50-goal scorers - including Maruk, Babych, Kehoe, Simmer
81/82: 10x 50-goal scorers - including Messier, Middleton, Stoughton, Vaive
82/83: 7x 50-goal scorers - was Lanny McDonald's 66 goal season really better than Ovi's peak?
This could go on forever. There are nobody's that scored 50 goals back then.
You can do the exact same argument with points and compare Crosby and McDavid etc (who have never scored more than 120 points in a season. Just to quickly skim through the 80's, did the following players have better seasons than Crosby or McDavid ever had (simply because they had more points?: Nicholls, Maruk, Kurri, Coffey, Yzerman, Stastny, Hull, Savard, Hawerchuk, Trottier, Messier, Goulet.
Half of Ovechkins career (10/11 to 16/17) was played in a time where there were only 5x 100-point seasons (SEVEN YEARS). Here's how many 100-point seasons there were per year in the 80's: 12, 13, 11, 12, 16, 13, 7, 12, 9, 13. You'd have to be dense to actually believe that there were 15x as many 100-point seasons in the 80's than from 10/11 to 16/17 simply because there were more great players.
