Five attackers with defenders, coach is under the basket with a ball. When coach yells "shot", defenders box out (hand to shoulder, butt to gut), coach checks positions, passes to one defender.
(Variation - coach is on the perimeter and shoots instead of passing)
coachesclipboard.ca - defenders are 3 feet in front of attackers, who are instructed to go either left or right towards the basket on "go", each defender blocks out using a front pivot, arm bar to the chest, and rear end to the thighs of the offensive player.
Tara VanDerveer - partner box-out - on "shot", hit before you turn and box-out.
