Clearly Curry is talented. I don't think he shoots nearly as much or as far from the basket if he played 20 years ago though. And who knows how good some of shooters from past eras would be if they were given that kind of freedom and worked on it in practice. Curry, Harden, Dame, and Doncic practice extremely difficult deep shots off the dribble that no player would even think about just 10 years ago. And it's because defenses have taken away easy threes and those shots are more efficient than an open midrange jumper. Coaches tailor their offenses to it.
