Blues Eye the Price Tag on a Draft-Day Move Up

The Blues are doing the kind of draft math that usually means somebody in the room is impatient with where the board might fall. Trading up is never cheap, and teams only go there when they believe the player is worth the pain of giving up picks, prospects, or both. St. Louis has to decide how aggressive it wants to be before the draft turns into a game of waiting and regret. The real question is whether the target is worth paying a premium to jump the line.
