everyone has a ceiling. shooting practice

may halp improve shooting form, and it may not.  I believe everyone in NBA spend time to improve their shooting form.  but what you see is what you get. 

there are talent shooter that you cannot copy such as Ray Allen, Stephen Curry, Novak...otherwise they wouldn't be called talented.

Players should not waste time in the summer but fans should not expect a player can turn around in a summer, that is unreal.
