Bloodlines aren't everything when it comes to the NHL Draft, but it doesn't hurt.
Prospects with notable bloodlines are always a bit more intriguing. The genetics are one thing, but the nurture aspect is also big. As one scout recently explained to me, the kids of former professionals pretty much grew up in a professional locker room. They know what to expect. They know how the level at which top players worked on a daily basis. Drafting with nepotism in mind is a terrible idea, but there certainly is reason to give a few "extra credit points" to prospects with family in hockey.
