The athleticism stands out because it’s something we haven’t really seen before, not at that weight, certainly not at that age. He looks like Jadeveon Clowney but even bigger and even more athletic.
But I don’t think he’s just all jump and dunk. He does look to have solid handles (dribble a bit high but he’s solid for a guy at his size and position), he has good dexterity and touch at the rim. He seems to have a plus basketball IQ, but consistently better compe ion could be a better indicator. And I do think his athleticism plays up because he plays hard.
The height thing will be interesting. If he’s listed at 6’7, he may really actually be closer to 6’5. What is he going to look like when he has to guard Giannis or Durant or Porzingis. If he’s got enough perimeter skill and improves his jumper enough, he could be pretty special. If he’s just the best athlete who plays PF only, he may just be a pretty good player who’s great for occasional highlight plays.
