I can think of three very obvious things Marcus can do to improve his shooting stats this year without changing his form… First… he needs confidence! That plays a huge role in bringing up numbers. It only takes the slightest hesitation to kill a shot. Marcus has to realize that just deciding he feels confident will begin improving his shot. If he needs any help with this he should chat with KJ. Man… he’s never afraid to take a shot from anywhere! Second… he should rethink his focus. Is his vision okay? Maybe worth an eye test. He needs to think more about where he is focusing… back of the rim? An overall vision of the rim? Does he envision a pathway for the ball? Third… he has to learn to relax on his shot. His arms should feel like spaghetti. Soft stroke. Follow through…
