Hockey: Exploring the back line

Player 1 runs into the circle and if the defender does not approach, player 1 can shoot at goal. Alternatively if the defender approaches, player 1 can play a one two with player 2 and then shoot at goal.
Player 2 needs to run out to make him/her self available for the pass from player 1.
Same practice on the other side of the circle (see h500188an).

Player 2(left wing) receives ball from the Player 1 (left midfield) and takes the ball into the zone, where the defender can try and win the ball. Just before player 2 loses the ball, he/she turns away from the RD and passes the ball to player 1. It is important that this player stays outside the 23m area and straight behind player 2. When player 1 receives the ball, he/she plays the ball to player 3, who runs towards the circle and uses player 4 + 5 to try and score a goal.
Every player then follows their own pass and next ball(player 3 to 4 to 5).

The player on the left passes the ball into the path of the player on the right. When this player receives the ball they continue to run with with it before passing the ball to the player on the far post who then has shot on goal.

The player passing to the far post continues to run after their pass and takes up a new position by the right post.

The practice can now start again from the other side.

Players in the middle pass the ball out to their respective wingers.

The winger receives the ball, and moves down the wing to then cross the ball back to the original passer, who has run into to the circle.
