New York Islanders Five Worst Player Personnel Decisions Ever

What are some of the worst decision that the New York Islanders have taken when it comes to their player personnel?
So what am I talking about when I say the New York Islanders ‘player personnel’? I’m talking about the on-ice product and the decisions the Isles took in trying to build the best on-ice product possible.
This list won’t talk about trying to sell the team to John Spanos. Or letting both Mike Millbury and Garth Snow control the team for an insane twenty-two and a half years combined. Nor will I be talking about Jack Capuano and his incredible six-year career with the Isles.
I wanted to list some of the Islanders most confusing decisions or biggest missed opportunities when it came to their roster. Where there players that they should have and could have drafted over the ones they inevitably drafted?
What about trades? Are there trades where the New York Islanders gave up on certain players or let go of some that had way more promise than the ones they would eventually bring in?
Or maybe the Islanders showed way too much faith in a certain player? Did that faith eventually come back and bite them in the rear end?
The answer is to all those questions is yes. The New York Islanders have made some questionable decisions in their 46-year history. These are the five worst ones.
