Watch as Coach Kim Barnes Arico explains and players demonstrate this "head on a swivel" defensive drill. The defender must be able to see both the ball and the player they are guarding at the same time. When a player is in a help position, their ball-side foot should be up and not flat, to prevent being screened. The focus is on getting up the line in proper position, jumping to the ball on a pass, being physical, and staying on the inside.
