Coach passes to 1 on the wing, 2 sprints to close out from under the rim, 1 jabs hard at the defender who must take the fake with his back foot. After a 3-count, 1 will pass back to coach, run to the back to the rim line and 2 takes his place.
See Defending - Close-out from gap.
a) after a jab step, 1 dribbles the ball and picks it up, causing defender 2 to pressure him with both hands up
b) when the attacker passes back to coach, the defender must assume a gap position, the coach then throws back to the attacker who will foot fake at the defender again before passing back to coach and rotating to the back of the line
