Assuming he plays 75+ games, I think he has earned the benefit of the doubt that he'll have another point-per-game season, breaking Gretzky’s record.
What I like about Crosby is how incredibly productive he still is at even strength (5th in the league over the last two seasons). Most players, as they age, rely more on the powerplay to maintain their production, but it’s been quite the opposite for Crosby as he still playing at his prime level in that regard. With a decent power play, he probably hits 100 points on the nose in 2022-23 and 2023-24.
I predict something like 82 points in 75 games this upcoming season.
