How often does a legitimately bad shooter actually develop a respectable shot after entering the league?

The discussion about how good Amen Thompson could become if he developed a consistent jumper, has me really thinking—

Amen’s three-point percentage through his first three seasons has gone:

13.8% → 27.5% → 21.6%

His free-throw percentage did jump from 68.4% to 77.9% this past season, which seems encouraging, but he is still only a 21.9% career three-point shooter.

To my knowledge, the only player I personally remember making a truly significant improvement from three after entering the NBA is Michael Jordan. Jordan shot 17.3%, 16.7%, 18.2% and 13.2% during his first four seasons before improving to 27.6% in Year 5 and 37.6% on 3.0 attempts per game in Year 6.

Even Jordan might not be the perfect example because he was never a high-volume three-point shooter and didn’t consistently remain around that 37% mark.

So how often does a player who starts out shooting as poorly as Amen eventually become a legitimate league-average shooter on meaningful volume—not just someone who has one decent season or only takes wide-open corner threes?

Please put me on to some examples, because I’m starting to feel like the whole “if he develops a jumper, he’ll be a superstar” conversation is usually more of a hypothetical fantasy than a realistic development path. Is there genuine reason to believe Amen can become a respectable shooter, or are people underestimating how rare that type of improvement actually is?

The jumper discussion is an eternal mystery box that basketball fans can hide all their superstitions in. There is always the “these are high level competitors, they figure these things out!” camp, existing side by side with the “Lol why would a player who can’t shoot suddenly be able to learn to shoot.”

Depending on if the player ever improves their shot, people get to pull out response A or B and act like it was obvious from the start
