Confucius say: Is grip in itself finger pressure? One cannot grip any thing without applying pressure with the fingers. Just feel like being a smart u know what.
The grip for the peel drop is between the thumb and the little finger, not between the thumb and three fingers used to spin the ball that are across the seam. If the ball is griped between the thumb and 3 finger, the thumb will restrict spin and cause a late release, which is called a fast ball, or a drop that doesn't move good.
