Windup Key

Throwing a football?

What is the key component for gaining distance when throwing a football? Is it the wristsnap, the followthrough, the windup or is it something else? I’m trying to gain distance on my throw. The ball seems to leave my hand prematurely. (grip too weak?)

you wanna let go right about behind your ear and then follow through with a lot of strength
