* The coach continues this pattern and the difficulty of the possession exercise gradually increases as more defends enter.
Once the ball is played out the roles are reversed.
1) D1 enters the grid whent he coach calls out 1, and he pressures the ball.
2) After 10 seconds of D1 defending on his/her own, the coach calls out 2 and D2 enters to help D1.
3) D3 then enters (sprints in) when the coach calls out 3. An so on.
