Agree with you ! II wouldn't even call this making a case for McQueen. You gave no evidence that he deserves to be picked this high and I have no idea why you think he has more offensive potential than the other 3 guys you mention. It certainly doesn't show up in the highlights or stat sheet. Back injury or not McQueen will never be a top 6 forward in the NHL. I wouldn't take him in the top 20.
Just don’t know where to see this amazing potential ?? A 6,5 guy taller bigger and older than other juniors who get 1 pt a game ??? Sorry NO
