Galchenyuk's a forward, and for the Islanders, this pick was a decision between an offensive player and a defensive player in Ryan Murray. Defensemen are harder to predict as they take much longer to develop than forwards, generally speaking, and that's a major reason why Lighthouse Hockey went with Galchenyuk.
At #4, it's not about filling a need -- not even a long-term talent depth need. It's about grabbing the player you think has the best chance of being a very good difference-maker. You can adjust depth disparities later; it's always easier to do that when you have the highest-quality assets possible.
Murray is a favorite among many readers here, and the other promising defensemen like Matthew Dumba, Jacob Trouba and Morgan Rielly have drawn attention. But for my money, if Galchenyuk is left on the board at #4, it's an easy decision.
