Should You Be Able to Drive Your Shoulder on a Drive?

Basketball is like the ship of theseus, but it still has parts that can't be touched. What are the component parts of basketball that are static and unchanging? And then what are the things that we can tweak and change? I want to be clear also, on the shoulder bump, because it's, it's named deliberately to sound very innocuous. This is not dipping your shoulder on a drive. Like you might see in basketball games for decades and decades and decades.
