All I’ve seen are highlights, so in other words a few seconds before he makes a shot. I mention that because he doesn’t look well-suited to play NBA defense. Doesn’t look to have a great lower body, either in terms of strength or mobility, and has a high center of gravity.
It seems a little off to call him a “power forward”, since there’s no power in his game. Better to call him a swing, or a stretch-4.
He appears to have a scorer’s mentality, a good stroke with a quick release, and some ability to shoot off the dribble.
