For what it's worth I like DJ Wilson, but I also have some worries about him. He has the trifecta of success - NBA size, NBA athleticism, NBA skill. He's very long (7'3" wingspan, 9'2" standing reach) with the mobility of a wing and the length of a Derrick Favors. He has explosive athleticism off both 1 foot and 2 feet. He is the perfect new age big IMO. His length and mobility will help him defend at a good level with Jazz coaching, IMO. He also has a legit NBA skill - he can shoot. I am completely buying his shot. It looks great and it goes in - both from 3 and from FT. His release is very quick too. I have no worries for his shot in the NBA. At the very least I think he can be a 35-36% shooter. He also seems to have good IQ which can be seen on his cuts. To me he looks like a very good modern day 4 prospect.
The problem with him is... the rest of his game is a bit raw and unrefined, which wouldn't be a problem if he wasn't 21 already. I wonder why he needed to become junior before he shined? I still like him and I still would take him no. 30 without much hesitation.
