You can't compare a forward to a defender.

Why not?

Two different positions. They are expected to play the game in completely different ways. Suppose to be in different spots at all time.

This is very nonsensical.

Or are you suggesting you can't differentiate between between McDavid and Kris Russel because they are playing different positions?

Of course one has to account for differences like usage and position. But we can do that.

I have Chiarot down as equally poor offensively as he is good defensively.
Järnkrok is better defensively than he is bad offensively.

There - comparison made.

Jarnkrok is good defensively because he stays on the blue line in the offensive zone or in front of the net in the defensive zone? You can't compare because a defenders game and a forward game are completely different

I compare them by measuring their isolated impacts on the shots their team and opponents take with them on the ice.

Chiarot reduces both by a few percentage - making him average. Järnkrok reduces shot for the opposing team more than for his own - which makes him a little better.

So you're saying Chiarot is an average defender when it comes to defending. And Jarnkrok is an above average defender when it comes to forwards? That's great, but it's not comparing them because they play two different positions.

No, I'm saying, as players and regardless of position, they have this impact on scoring.

That's fine, but it's not the same. You can't compare them.

For me Seattle wins this trade. Seattle gets 3 draft picks even though they might not do a lot the players they get might help out with Seattle’s AHL team once they get one. Calgary continues to try and make a push for the Stanley Cup and Janmark will definitely help with their bottom 6. Janmark didn’t play very well with Seattle so for me this trade wasn’t surprising. Seattle wins though because in this trade Calgary 100% overpaid for Janmark so Seattle wins.
