Just want to clarify
22-23 Kraken: 46-28-8
22-23 Sharks: 22-44-16
And the argument you're making is that the sharks were "much better"?
It is convenient to look at one season and also ignore the team makeup. Meier has played on Sharks teams which have had much more skilled players than the Kraken ever have. Seasons in which Meier has had 30 or higher goals:
2018-19
Brent Burns D 82 16 67 83
Tomas Herti C 77 35 39 74
Logan Couture C 81 27 43 70
Timo Meier R 78 30 36 66
Joe Pavelski C 75 38 26 64
2022-23
Erik Karlsson D 82 25 76 101
Logan Couture 82 27 40 67
Tomas Herti 79 22 41 63
Timo Meier R 57 31 21 52
Even the 2023-24 season where Meier had 28 goals with the Devils.
Jesper Bratt L 82 27 56 83
Jack Hughes 62 27 47 74
Nico Hischier C 71 27 40 67
Timo Meier R 69 28 24 52
Compare that to how many skilled players the Kraken have had. The only season where Meier led the Sharks in points was 2021-22. That was the season where there was no Pavelski, Karlsson only played 50 games, Thornton was done, Burns had started to show his age. Compare that to McCann, who has led the Kraken in points every season.
Ofcourse, this does not guarantee that McCann will hit 40 or even 30 goals on the Devils. There is no guarantee that can be given about any player changing team (eg: Rantanen). But you need to do more than just look at one season.
