The first step in this process is adjusting the placement of Turner's left hand - his off hand - on the ball. This detail, which involves no more than an inch or two of movement, will fix two problems: It will keep Turner from using his left thumb on the release of his jumper (the thumb never being an ideal addition to any shot). And, thanks to physics, that adjustment will automatically tuck in Turner's left elbow, which has a tendency to flare.
