This is where I'm at.
I wouldn't draft Luke just because he is Jack's brother, but it isn't like he is some middling prospect either. Most have him somewhere between the top player in the draft to Top Six. So if you get him at four, it keeps Jack happy, and you get a guy with a lot of upside who is more or less drafted where he should be, it feels like a win-win. If he is gone when the Devils draft, so be it, but I am more than happy getting a slick skating, highly skilled defensemen at #4 overall with some good, albeit unrefined, defensive instincts.
