All teams burn draft choices.
IMO.I don't think it is done on purpose. It's up to the drafting scout to make sure he has all information to present to the team. The biggest consideration, this player will sign when drafted. I wouldhope that when presented an opportunity, all players (mine included) make their postiions clear as to their intentions. If any player is told that he would be able to postpone duty and go for it, then so be it, and I would agree the fault lies on mixed signals given from the Academies.
That's where asking about policy comes into the picture.
A large part of the draft is about signability, not always talent. You will understand that someday soon.
Let's not make this a drafting issue.
