I will preface this by stating that I've never seen this kid play.
There are quite a few players who at his age can be best categorized as ball dominant scoring guards, which is what I imagine he currently is. He appears to have exceptional athleticism and skills so whether it is due to choice or due to need. At this point in his career, his having the ball in his hands and also being the primary scoring option is not necessarily a critique of his game.
My personal opinion: if he wants to develop a full game, where he can at any time assume the role of a one, two or three, there would be no better destination than here. This should pay dividends in the long run as his movement without the ball, his passing, his understanding of spacing and his defense will improve tremendously, making his transition to the NBA (and more importantly, his ability to draw a second contract) far easier.
If he wants to be coddled, if he wants to be the guy, if he wants a large NIL bag, there are better landing spots than here.
