Well I was more referencing to your NCAA exemple, because I've never seen a player from there being NHL ready at 18, and that is pretty much what Milhouse was saying with being a top pick instead of a middle round. To be honest, I find it very strange myself that the guy signed a 3-year deal over there, being projected at such a high pick and likely to play in the NHL. But then, HuGo would know more about this situation than all of us anyway. All we can do is some guessworks
To answer your last sentence, the risk here is to waste a very high pick for a guy that could
possibly never come here. That would have more dire consequences than drafting another high ranked player.
