Yes maybe, but even then there is no any hidden intelligent plan to draft only forwards as you suggest. It was just a coincidence that Zadina fell for them, otherwise they've most likely picked one of the D you would think.
What concerns me is the fact that they're going offence first, and that leaves many questions if they're going to get that much desired top D. Via trade, it's all about luck to have right D available and match every other teams offers. With top pick, it's a long wait. And besides drafting offence recently, we still lack that elite C too.
When you evaluate well and find elite talent to key positions, you have best chances to end up having those much needed core pieces for next 15+years. I'm not sure if they have any specific plan at the moment, last two drafts and they've ended up pretty much everything else but elite D/C prospect in the system.
