New York Islanders How Garth Snow Compares to Every NHL GM

Playoff Success
This will now rate how well a team has done once it has reached the postseason. The regular season grind only serves to get a team to the year-end tournament for the Stanley Cup.
I didn’t build a ratio for this one. I felt that it was only fair to properly reward a GM like Ken Holland that has made the playoffs year-over-year.
What I graded were the number of wins over games played, the number of series wins, conference championships, and Stanley Cups. Because these aren’t worth the same I weighted them based on how frequently they occur.
The wins ratios were already weighted, series wins got a quarter point each, conference championships a half point, and a full point for Stanley Cups. So the formula looked like so:
"Playoff Success= (Wins/Games Played)+(Series Wins*0.25)+(Conference Champs*0.5)+Stanley Cups"
Can you guess where Garth Snow finished? 16th. “Hey! That’s not bad! That’s mid-table” you might say. Sure, that’s true. But consider that there are three GMs that haven’t been there a full year yet. That reduces the field a bit.
Also, consider how there’s a strong correlation between tenure and playoff success. Meaning that the longer a GM stays in the job the more likely he is to get some postseason success. With how long Garth has been in the job, he should be much higher in this ranking.
Instead, he’s hovering below Jeff Gorton in 15th place and above Calgary’s Brad Treliving. GMs who’ve been there since 2015 and 2014 respectively.

This ranking just looks at two factors, it doesn’t even consider a GM’s drafting history. I wanted to focus on the success a respective GM brings to an organization. It’s clear by this that he doesn’t. Assuming you didn’t already know that, here are some numbers to quantify it.
