Wikipedia lists him at 6'-5" in one place and 6'-6" in another. In either case, he certainly does move well, handle well, and see the court well for a player with that size. Hard to gauge the competition. It did not look to me like he was all that fast/quick, yet he was easily getting everywhere he wanted to get against that competition. Really just blowing right by every defender.
Hard to say really if he is better than say Dalano Banton (for example), based on the highlight reel but definitely an interesting player.
