He is a 3/4 who can guard 2-5. I see a lot of Danilo Gallinari before injuries limited his mobility. I've also heard Bogdanovic with better ball handling. He's a sure bet as a starting small forward because his shot has become so smooth, but the ceiling could be in question. If the Cavs are picking outside of the top two, I'm pretty sure he is the pick.
It is honestly a tough call, watching him. I think he's best suited to be a 4, relative to his matchups at the 3 at the NBA level......but it will also be pretty tough on him physically until his body matures. He seems to have the requisite length to be a 4 and his post defense looks solid for his age / frame.....and playing at the 4 would make him more valuable as a ball handler and lower the skill level needed to be effective.
He's really young......so his handle can improve but some of the recent pressure leads me to believe he's going to have tough sledding against the better 3's offensively......and if you remove his avenue to creation, I'm not sure he's a very interesting prospect......especially at the top of a draft.
I have to say, I don't think he's nearly at the level of a young Gallo in terms of shot creation. Before Doncic, Gallo was arguably the best pure scoring prospect ever to come out of Europe. Deni really seems destined to play a complementary role offensively, IMO.
