If someone has athletic talent and some basketball skills, then it boiles down to 2 things. How hard is he willingto work to achieve greatness, The other is being in the right system to showcase those skills and allow you to use the athletic talent that you have. If you are in the wrong system then you are not allowed to use the talents and skill that you have, and you suck. Transfer to a system that allows you to use you to use your talent and skills and sometimes that player that sucked at one school becomes a star at another. Most coaches have huge egos and think their style is the only thing that will work, at the expence of some of their players.
