Two defenders work inside a circle of players with one ball. The red players must pass the ball around the group and try to keep possession. The two defending players must work together to mark the ball, keeping the 3ft distance, while the other defenders 'zones' the space. So, if Red 1 receives the ball, Green 1 (the nearest defender) calls "ball" and goes to cover the ball and Green 2 moves back, calls "hole" and zones the area.
