Islanders are going to be very disappointed in what they get from any team. There are so many examples of players getting low value in return ie. Kessel, Seguin, Hamilton. And none of them requested a trade as well as having it go public. They can preach all they want that they can wait till a good deal presents itself but it's obviously time sensitive since its for personal reasons. This trade is only going to take awhile because Snow has to choose which low ball offer is best to stomach.
You can throw Kesler into the mix as well. No way is Snow getting a top 4 d man in return...that would just be a lateral move for the team trading with the Islanders. Snow doesn't have much leverage.
