This guy will be interesting to keep an eye on - he's a good prospect. I love what I've seen of Ben Simmons though - he's one of the prospects I'm most excited about in the next 3 drafts, so i'm not putting many people above him, but hopefully this guy has as much potential as you seem to think.
I agree with Nowee though, take highlight videos with a grain of salt. Rely too much on them and you'll be lobbying for the C's to draft Yi Jianlin Jr.
