When Islanders had a high pick they generally seemed to make a "consensus pick". Nino was the top forward available in 2010, Strome while not the top player left in 2011 was considered in a group of 4 players to be selected 5(I would argue he was third behind Hamilton and Couturier), Reinhart was the Best defenseman/2nd Best Player(Forsburg) in 2012, Dal Colle was the best player left in 2014.
I do not remember some of these the same as you. I do not remember Reinhart being the best defenseman left on the board. Guys like Trouba, Reilly, and Dumba were ranked ahead of Reinhart. While I will give you Nino I always felt that year Snow should have drafted Fowler who was never expected to fall that far. I still believe Snow wanted Johansen that year and did not expect him to get scooped.
MDC was certainly the consensus pick. Strome in my opinion was even the consensus pick as well. It is painful to look back at these players thinking how NONE of them turned out for the Islanders.
I am only quoting your post to add on some additional info, not that I necessarily disagree with you. Tavares leaving certainly hurt the franchise, but whiffing on all of these picks is what TRULY hurt the franchise. This is why I cringe when I see people say how Snow left a good team for Lou. Snow left a battered down team for Lou who had zero direction, lost their franchise player, and due to Lou being a true leader and bringing in Trotz (along with some key acquisitions) did this team have the three year run it just did.
Does Lou have his problems? Absolutely. Should Snow even be allowed to be a waiter to Lou? No because I would not want his stink rubbing off on Lou in any sort of ways.
