Watch Dell Isola, former Fordham University and present New York Giants centre, as he prepares to snap the ball. Dell's right hand grasps the ball much as a forward passer would do, gripping his fingers over the laces. His left hand, a little to the rear of the ball and under, serves only to steady his passes, which are made almost entirely with the right hand, enabling his fingers to impart the spiral as it is snapped to the backfield. In this day of direct passing, instead of having the quarterback crouched just behind the centre, accuracy and a complete knowledge of signals and backfield assignments is essential for every centre.
