Quoting: Carleton
There's a difference if you're specifically looking at RAW numbers like xG and Corsi because they have more weight on how the team is performing. But when you funnel the raw numbers into a system where you control quality of comp, quality of teammates, minutes played, deployment, etc, you can create EV defense and EV offense percentiles based on similar players in the same roles and situations.
You're just taking the numbers and putting them into percentiles based on how that player has individually performed vs his counterparts.
The issue I have is all of those variables are dependent on 2 things. Teammattes and schemes.
For instance, Corsi I mainly shots for while on ice vs shots against. The Blues are bottom 5 in the league of shots taken. Meanwhile the flames are 7th.
Nick Leddy Paraykos primary partner has taken 42 shots this season.
Rasmus Anderson has taken 95. Over double.
I’m not trying to knock Weegar by any means, but to outline how these things are not exactly as independent as possible and are reliant on teammattes and overall game plans.
I quite like Weegar as a player.
But pair that with Paraykos 35% ozs versus Weegars 53% and that Calgary doesn’t have to push the Weegar Anderson pair out there every time a superstar comes in to town because they have a Hanifin, Tanev pairing. You can see where stats don’t tell the full story.
I’m not trying to advocate Toronto or Edmonton should trade for Parayko. I’m not trying to advocate that the last 2 years of Paraykos deal may not look so great. What I’m trying to advocate is that there is a loud group whenever it comes to Parayko and it’s mainly in the analytics community that isn’t getting the full picture.
