Here is what the legends say. The basic factor in all good golf is the grip. Get it right, and all other progress follows. It is impossible to play good golf without a good grip. A correct grip is a fundamental necessity.
Good golf begins with a good grip.
Pick up a club and take your best grip. Wiggle the wrists. Relate the clubface to the wrists. The ball and the clubface are connected for a brief period. Clearly, the wrists and clubface must move as one until the ball is gone.
