The problem with the NBA these days is how young players are being drafted. Nobody knows, not even scouts and GM's, how many of these prospects will develop. For example, Giannis is 21, Parker 20 and Vaughn 19. Those 3 could all be playing in college. Many hope Giannis and Parker develop their shots, but it is not a guarantee. A good coaching staff to develop these young players is key, I think the Bucks have that.
