His defensive metrics suggest otherwise, so your eyes are probably decieving you
Posting my reply here since in the other thread it's Marner vs Heiskanen, so I do not want to go off topic in that thread. Anyways...
Curious on what defensive metrics you are referencing that suggests Dahlin is better defensively?
In 2018-19:
RAPM xGA/60: Dahlin -0.051 > 0.022 Heiskanen
RAPM CA/60: Dahlin -0.47 < -2.24 Heiskanen
GAR EVD: Dahlin 2.2 < 2.4 Heiskanen
In 2019-2020:
RAPM xGA/60: Dahlin 0.022 < -0.075 Heiskanen
RAPM CA/60: Dahlin -0.02 < -0.9 Heiskanen
GAR EVD Dahlin -0.5 < 3.9 Heiskanen
Let's both season together 18-20:
RAPM xGA/60: Dahlin -0.029 > -0.012 Dahlin
RAPM CA/60: Dahlin -0.33 < -1.77 Heiskanen
GAR EVD: Dahlin 1.7 < 6.3 Heiskanen
So from this data I don't think the metrics suggests Dahlin is better defensively. It seems Heiskanen is better at limiting chances for his team than Dahlin over the course of their career. Even with Dallas being strong defensively at even strength potentially benefiting Miro, the gap is large enough for me to view Heiskanen as the better defensive player.
You keep making these claims that metrics suggests Dahlin as the better defensive player, but you never back up your statement with any metrics. Now may you present the analytics that supposedly paints Dahlin as the better defensive player?
