In order to throw a football better the first thing you need to look at is your grip. Where do you place your hands on a football. You will need to place your hands as far back on the football as possible without getting too far away from the threads. Place your second to last finger and your pinkie finger close to the threads with your middle finger and your forefinger close to the tip of the ball. Your thumb should be directly behind the ball, right underneath your forefinger.  This will improve your grip.

The second thing you need to do is to have the ball placed up high above your head. Now what you are going to do is lead with your chest and shoulder by stepping into your throw. Now bring your chest and shoulder forward, followed by your elbow and then your hand. When you release the ball it is going to come up off your fingertips. Now when you release the ball your arm will come down from your shoulder to your pocket. That's how you should throw a football.
