Canyon Berry did it and shot 88% at Florida his senior year. He graduated in 2017.
shot over 80% for his career.
On the Podcast mentioned by 06, at least I think it’s the same one I heard, Rick Berry said he talked to Shaq a out it.
Shaq told him he’d rather shoot 0% the modern style than be a good free throw shooter underhanded.
Its actually a fascinating listen. They talk about the physics of it and how it just makes more sense when it comes to the science behind it.
Berry claims he can turn any poor free throw shooter into a good one by teaching his method:
I wouldn’t think it could be done mid season but it might be worth a try during the off-season.
I don’t think a player would do it if it allows them to shoot 50% but I think if a guy like French could learn to shoot 75% they would make the change.
