To throw a perfect football spiral, grip the ball firmly with your fingers on the laces (NOT in the palm of your hand) and close your fingers, rather than the palm of your hand, around the ball. Rest your index finger near the tip of the ball or the second lace, keeping the grip comfortable and balanced. Stand with your shoulders turned to the sideline, plant with your front foot, rotate your hips and shoulders and throw. Release the ball at around ear level, snap your wrist and then roll your fingers off the laces. Follow through in the direction of the target. Batting the ball with consistent grip, consistent wrist rotation, and body mechanics will get a tight, accurate spiral.
