Roster decisions based on WAR ratings

Very interesting analysis good job friend!

It is important to note that the WAR ranking is very dependant on the team's depth and/or depth in the observed position of the player and/or the team. (correct me if I am mistaken)
That said, the overall ranking of WAR/82GP for Tomas Tatar in MTL is actually the highest for the team, but in a different team, with more depth, his score would be lower.

That's a number GM need to observe before signing or completing transactions but they can't fully rely on it, they need to picture that new player in their organization.

In relation to what you said, Matt Duchene has an overal score of 42, yes, but in MTL that score might just improve. In the same perspective, Gardiner is a 15, but he might not be a great fit to play with Weber or Petry, thus reducing the overall score. In that respect, Karl Alzner did not have such a bad rating before MTL signed him, but he didn't fit.

Food for thoughts!

The transferability of these numbers is a good question. I'd first reiterate that these are not ratings, but rankings. There is one RD in the league ranked at #8, and it's Weber.

Now, does playing for a bad team, or being buried in the lineup have an impact on these rankings? Probably, but not necessarily. Thompson for example was 160th when he joined the team, playing 4th line minutes on a bad team, he's now 186th. Not good. Weal on the other hand was 120ish, he's now 67th. He was in fact better than his numbers showed.

The case about Duchene: he's been 40ish all year, but he was playing for a bottom feeder team, right? Well Stone was a top 10 for most of the year, playing for the same team. Heck, if I'm not mistaken, Dzingel had a better ranking than Duchene when they were playing in Ottawa. To me, all the hype surrounding this player doesn't match the numbers. He might be the best C of this year UFA crop, but he's not worth more $ than comparables like Domi or Danault.
