We'll have to see how Ben Simmons develops. He has incredible skills, but because of his need to have the ball in his hands at all times, he will need to become the unequivocal leader of his team...and his team will need to be good for him to be considered 'transcendent.'
Brown on the other hand has incredible athleticism, already defending at a high level, can drive to the basket at will, and is shooting the 3-ball with some consistency. He also has a top-tier motor and will to improve his game like the best of them.
I understand that Simmons is a more talented player than Brown, but how each of them develop and how much each of them want 'it' will eventually show who the better player is. No matter, I am happy to have Brown over anybody else in the 2016 draft class.
