Green: Watch the ball all the way into your hands!
At the last crucial moment, a running back or pass receiver will be MORE LIKELY TO LOOK AWAY from the ball and look toward the direction he wants to run BEFORE GAINING SOLID POSESSION OF THE FOOTBALL and, therefore, miss or fumble . . if he tells himself NOT to look away.
Saying what I DO WANT TO DO gives my brain the best possible chance to make my body execute each step of the play in precision fashion.
Coaches: Tell your players to, "Watch the ball all the way into your hands before looking anyplace else!"
