That really depends how you look at it.
Let's say Schultz becomes a solid top 4 defenseman: You say that it doesn't matter because we did not get anything for him. That's true to an extent, but also wrong at the same time.
I personally think it means we have a good scouting department. Him leaving the way he did isn't on them. How do you know predict a kid's character being poor when he's saying all the right things? If he develops, I think it's damn impressive on our scouting department. The fact that we got nothing for him/outta him doesn't matter IMO. Not when evaluating how we draft in the 2nd round anyway.
All our drafting team can do is try and pick the players, it's up to Murray and the coaches to get "value" out of them. I personally think we should value picks more than others, because frankly, I think Murray has been pretty good with these picks. Even if the prospects are traded, their is still plenty of value in them.
I don't know, there's really no clear cut right or wrong answer.
