A lot of kids seem to have odd shooting mechanics in basketball. While playing yesterday, I was holding a towel to wipe my face with my non-dominant hand. I was still able to guide the ball on the shot with the towel in my hand (with my dominant hand doing the shooting), but I wouldn’t have been able to do that if I was a two-handed shooter, like some kids.
Idea: If you want to learn to shoot one-handed, hold something in your non-dominant hand while shooting. A small towel is probably about the right size.
