Lol at ej117. While IN THEORY, what you say might be true, in reality, most people simply don't have the ability to shoot 90% in the context of nba games. Yes, that's correct. In addition to the practice you keep talking about, there is also an inherent ability to shooting. And just like running, jumping, dribbling, strength, and anything else you can think of, some people are born to be better shooters. Obviously you have to take advantage of this ability but that doesn't change the fact that some have an advantage.
