Some quarterbacks place the middle finger along the laces as well. It depends on how large your hand is and what feels most comfortable for you.
You’ll need to experiment some to see what feels the most comfortable for you and your hand strength in terms of your index finger placement. Depending on how big your hands are, your finger will be closer to your other fingers, or the tip. [3] X Research source
Don’t “palm” the football. Try to keep space between the center of the palm and the ball, or you’ll increase the chances of a wobbly throw. Keep your hold firm enough to rotate your hand without the ball slipping out, but not so firm your fingers start to get tired.
Distribute your weight so that it’s back on hind leg. Good passes need to be stepped into, so distributing your weight back will allow you to put more power into your throws as you wind up. The foot opposite your throwing arm should be forward, aimed at your target in the direction that you’re throwing. It’s also good to keep your feet moving, “buzzing” them to stay on your toes. Never stand flat-footed when you’re throwing the football.
Keep your elbow at a 90 degree angle at all times as you cock the ball back to throw it. Rotate your throwing arm at the shoulder, pushing it straight back, but keeping the football and your hand pointing up. Throwing the football involves your whole body, using it in one fluid motion to twist yourself into the throw. Step forward with your front foot, pushing your non-throwing hand out in front of your for balance.
When you release the ball, spin it with your fingers to initiate the spiral. As you step into the throw, pitch your throwing hand forward, spinning the ball as you release it. Basically, you want to use your fingers to roll the ball out of your hand. Make sure that your hand and arm extend so that your index finger is the last one on the ball. Some football players like Philip Rivers and Tim Tebow use more a side-arm style of throwing the ball to throw spirals effectively, while other quarterbacks like Joe Montana have a more vertical throwing motion. Most quarterbacks fall somewhere in between.
