Should the Blues trade NHL player Rick Nash? The question is not whether they should have; it's whether they could have. They couldn't. Why? Let me fill you in on a trade secret: Before being dealt to the New York Rangers last July, Nash did not play for the Blues; he played for the Blue Jackets. Same league, same conference, same division even. Different teams though. One is in St. Louis; the other is in Columbus, about 400 miles east.
NHL managers may know the tricks of the trade, but not one is so skilled a magician that he can pull off trading a player that isn't even on his roster. If he could, it'd revolutionize sports.
