Obviously it's not a direct comparison, but I have heard some pretty old hockey minds compare him to a 16 year old...wait for it - Wayne Gretzky.
Obviously, he isn't the next Wayne Gretzky, but there are similarities. Both are lanky kids, neither one stands out on ice with McDavid/MacKinnon skating or Matthews/Bedard shots. He has a ton of deception and incredible IQ. His hands are also extremely good.
I would echo what others have said that he *could* be a kucherov type player someday. Long way to go, but he has been dominant at every age for multiple years now, borderline generational even
