Here's a good 20 minute scouting report on him. A lot of absurdity, but some little things stand out to me. His ability to get deep into a low guarding position at his height is really impressive, given he stays mobile while doing so. Even if he does get beaten off the dribble, he is so quick and long that he can recover on almost every possession.
I think as a rookie on defence he will be like a huge version of Evan Mobley. Still able to get pushed around, but with the instincts and BBIQ to counter it (alongside absurd size and length).
