O3 has the ball, but D9 and D10 block the passes into midfield, so O3 goes sideways to O2. D slides across together.
O2 forces a pass into O9 between the lines. As it travels, D6 and D2 close in on O9 from either side.
O9 receives with their back to goal and no room to turn. D6 steps in and wins the ball.
D6 plays forward into D10's run past O7, into the space between O3 and O4.
D10 is running at O's back line. D won the ball while still in shape, so there is no gap behind them for O to attack.
