You went from where do I start to one item. Okay.
Like I said before, you're unlikely to have a forward be any sort of impact in the upcoming season just like a defenseman. That means you're looking at 2017-2018 for any sort of significant input from your draftee, forward or defenseman. You can argue that a forward might be more ready in that season than a defenseman, which is fine, but let's not pretend like the defenseman you get at #8 is going to miss the contending window. "It'll be a forgotten pick when we're hoping to contend" is outright laughable unless you think this teams window is the next two seasons.
