Justin Quinn recently wrote in Celtics Life about Gordon Hayward shooting a basketball from a chair on the court. The question was raised as to whether doing that would adversely affect his shooting form for the future. The quick answer is that the Celtics staff would not have him do that if it was harmful in any way. My answer as a 26-year Personal Trainer specializing in Sports Conditioning is the same. As a matter of fact, what he is doing helps retain the basketball-to-hoop muscle memory that he has, and it can even improve his form when he returns to the court.
