There’s a reason that Anthony Morrow’s jump shot is so deadly. He has nice distance above the ground to avoid blocks. Morrow shoots a good distance above his head so that he has a clear view of the basket and bends his arms enough to produce an arc on his jumper. Morrow also grazes the ball with his left hand in order to produce enough spin on the ball so that it has a higher chance of rimming in. All these factors combined result in a deadly jumper.
Morrow’s distance above the ground on his jump shots is a key factor in why it is so good. This allows him to shoot over larger defenders and generate power from his knees. Then there is the distance the ball is above his head when he shoots. He gets the ball high so he can see the basket well. Morrow also bends his arms so he can produce a rainbow delivery which has a higher chance of going in than a line drive. Morrow is also able to generate spin on the ball by grazing it with his left hand. Spin makes it so that the ball has a chance of going in when it makes contact with the rim.
There is a reason that Morrow is one of the best pure shooters in the NBA. He has the highest 3 point shooting percentage in history and amazing form in his jump shot. Morrow is a constant target for double teams and reasonably so.
