Crosby will be toast in this belief within 2 seasons and 4 seasons max.
When McDavid has 4 Harts, 6 Lindsays, 7 Art Rosses, 400 goals/1100 points through 10 seasons, has been top 2 in both raw points and PPG for 9 years in a row, likely top 5 in Hart voting for 9 years in a row to go along with at least 6 nominations, and at least a Cup and a Smythe maybe even 2, all he’ll need to do is compile stats for the second half of his career.
And when that’s all that has to be done, there’s no point waiting to move him into the top 5 and it will be definitively over Crosby and the other 7 players or so who all have their own compelling cases.
