Ignoring Dahlin, I think at least 2 of the teams ahead of us that drafted defensemen might regret it. On a side note about the Islanders if they only had 1 pick I hope they would have picked Dobson before Wahlstrom and the only reason they picked Wahlstrom was because he was easier to push for PR purposes(ie a high scoring American)
Hard to say. Without getting in to "who is the better prospect", I think Dobson is more important but it's possible the Isles FO would have preferred Wahlstrom due to Eberle's uncertain future and the possibility that Ho-Sang doesn't work out. He has the size to suggest he could be ready quickly, which would be big if Eberle walks at the end of the year and/or if JHS struggles.
Dobson is something we haven't had in a long time, though - and that's a guy with legitimate #1D upside. Even when Big Griff was at his peak of hype I remember more "solid #2/high-end #3" predictions. I think they would have still chosen Dobson but you never really know.
I'm just happy to have both!
