Also, what exactly happened last season?
Lowest on ice shooting percentage of his career at even strenght and in general was quite different than the average since scoring went up again in the nhl.
That said, he had 78 ev points in 80 games last year, 70 in 74 games this year, virtually the same, the difference is all in the much more effective power play.
McDavid, pts per 60 minutes at ev
22-23: 2.76
21-22: 2.61 (considering the 10.7% instead of his usual 14-15% shooting percentage seem like bad puck luck could explain a lot of it, if it was not some hand-wrist or something else in the kinematic chain injury damaging his shooting)
20-21: 3.57
19-20: 2.89
18-19: 2.82
Still winning Ross when things does not go well (would it be Jagr playing ljust 63 games and still winning) or puck luck, show a level of separation with the pack is going on, usually winners do it on a perfect storm kind of season, play almost all the game, power play went well, their line was firing and in general having a top 2 season if not the best season of their career, etc...
Jagr-McDavid does it on a "down" year and obviously Gretzky-Lemieux.
