The goalkeeper passes to O2. D9 presses O2, D10 steps up to O6 and D7 closes in on O1.
With no safe pass forward, O2 plays back to the goalkeeper. D9 follows the ball.
The goalkeeper passes to O3 on the other side. D10 leaves O6 to press O3, and D8 closes in on O4.
O3 plays inside to O6, who is free now that D10 has left.
O6 turns and passes to the coach, C, past the halfway line.
That is a point for the build up team. If the pressers win the ball, they attack the big goal, then the goalkeeper restarts.
