I think Hughes has the higher potential and Stuetzle's recent production proves as a bias in voting. Yes Stuetzle is producing better at the same age but how quickly you become good and how good you become are two different things.
If you think Stuetzle's potential is on par with Hughes' than by all means, vote Stuetzle. But I feel that Hughes' skating is the most elite talent of both players and this will work to Jack's advantage, in a game going towards finesse and faster-paced skating.
Jack Hughes' skating is only rivaled by few, McDavid and Barzal being two of them if not the only two. And Jack is 19. Let him get his man strength.
