Re: 3 Point Shooting
One tip I could say is to lower your elbow on the release, to provide more power for your shot, kinda how Nash shoots the three ball compared to midrange. His elbows are lower in the three ball. I read this somewhere and been incorporating it with my shooting in this new league that I am in where the three point line is like 2-3 feet further from what I am used to lol.
But yes bend your legs, follow through, lock your elbows as what other posters have said here.
