Five players come to mind.
Quinn Hughes: A complete rover of a defensemen. He’ll be one of the best skaters, stickhandlers and playmakers in the NHL, but he wouldn’t know where the defensive zone is if you put up a sign for it. I also don’t like his hockey IQ at either end of the ice. He’ll put up a lot of points, but will give plenty back, and be a low end NHL’er.
Hayton: Another player whose hockey IQ I don’t like. It’s not that bad, but it’s a lot worse than the reputation it gets, in my opinion. He’s above-average across the board, but I don’t see the talent in any part of the game to be more than a 2C.
Samorukov: Classic case of an older CHL’er dominating in his last year in the league. I’ve always thought he’d play in the NHL, but I don’t buy that he has high upside. I don’t like his puck skill or vision.
Poehling: Another who will play in the NHL as an average player, but low-end upside. Small sample sizes don’t prove high upside over mediocre play in high sample sizes. I even think he’s getting the benefit of the doubt for his NCAA play in a way that others don’t get.
Zadina: Everyone overrated this guy to some extent. He’ll be a top six guy, maybe a top line guy, but I think he lacks the high-high end upside. Mediocre skating, size isn’t the advantage most thought it might be, not a line driver.
