that seems improbable that a person can accurately get a ball into a cup consistently as a variety of trick shots with no mistakes. Including situations where the setup is randomized (like sliding a glass out and bouncing the ball into the glass.
I don't doubt a kid could practice a few shots and become reliably good at them.
But the sheer variety and even launch variation (he catapults one off a skateboard, which would introduct new variables and skills into the mix) seems improbable that this is a legitimate as shown.
At best, we may be seeing the successes, and the video neglects to show the 10 takes it took per shot.
