Currently, Kai Sotto's skills aren't enough to take him to the NBA and that may be the reason why he haven't got drafted recently. He got the height and advantage compared to the other players who are seeking NBA but he need to do more so that he will rise above others. Kai is now groomed up and his teammates even help him achieve his dreams. But Victor is different, teams in the league are already drooling to get him. Let's see who will be the lucky team soon.
Height is his asset but that won't be enough.
I've seen rookies that has got the height and not that much thick but performance wise, they can really make plays inside while him, he seems so lousy and needs more training.
IIRC, there were G League invitations for him but he has chosen other priorities than it. I guess if he went through g league, he's got more chance of being in.
