In the NBA, the highest level in the League, there's never been any standard shooting posture.
Those highly skilled shooters each have their own unique release characteristics, even quirks, according to their physical condition.
Like Gan Guoyang's straight-arm wrist shot, generally, people can't use it at all. It's stable, but it requires too much strength, unique to him.
Other so-called straight-arm shots mainly rely on arm strength. Like Gan Guoyang's shot, which mainly uses wrist power, maybe only O'Neal can do it, but O'Neal is not accurate at all.
Then there's the very standard and beautiful shooting posture of Bucks guard Ray Allen. Many people call him "textbook style" because of his shooting accuracy and beautiful posture, but that's a huge misconception.
If Ray Allen's shooting posture is a textbook, then this textbook is undoubtedly a failure, because Ray Allen's shooting posture is also too difficult.
