Vegas has a thin prospect pool but I question how much this particular person knows about it.
Korczak was better than Whitecloud and probably Hague when he played in the NHL for 26 games last season. He was only sent back because we had eight top six defensemen last year and cap issues and he was the only one who didn't need waivers. He's an NHL ready defenseman right now who could even break out to a top four next season.
So the fact that he's sixth on this list and way behind Cormier in first, who is a good distance behind where Korczak is in development, makes me think whoever put this list together doesn't know much about the Golden Knights prospects. Can't speak to what they may not know about others.
Let alone being behind Denisenko who is not an NHL level player.
