he needs to work on his post presence (mainly D), his body, his mid range and his athleticism (stop being stiff).
if he can make significant leaps in two of those categories I still think he can play in the NBA.
he did really well with his 3pt shot this year. I think he has the mindset to accomplish his goals.
