That seems like a weird example given that Crosby's stats are stagnant since 2015-16.
Where is this increase is "league wide scoring" in Crosby's stats?
Year | GP | Pts | P/GP |
2015-16 | 80 | 85 | 1.06 |
2016-17 | 75 | 89 | 1.19 |
2017-18 | 82 | 89 | 1.09 |
2018-19 | 79 | 100 | 1.27 |
2019-20 | 41 | 47 | 1.15 |
2020-21 | 55 | 62 | 1.13 |
2022-22 | 69 | 84 | 1.22 |
I think you are conflating "league wide scoring trends" and a career year. Karlsson had 2-3 great years. Miller just had one great year.
Are you serious? The increase in league wide scoring is
right there, look at Crosby going from averaging 1.11 pts per game in the first three seasons to 1.19 per game ages 31-34.
Now, individuals may have tons of reasons why their scoring goes up and down between seasons, but you still probably brought a pretty good individual example with Crosby.
A better way to look at a trend however is looking at a larger sample size:
2015-16: 5 80 pt scorers; 1 100 pt scorer
2016-17: 7 80 pt scorers; 1 100 pt scorer
2017-18: 21 80 pt scorers; 3 100 pt scorers
2018-19: 28 80 pt scorers; 6 100 pt scorers
2019-20 (covid): 9 80 pt scorers; 1 100 pt scorer
2020-21 (covid): 2 80 pt scorers; 1 100 pt scorer
2021-22: 34 80 pt scorers; 8 100 pt scorers
