Making sure 1,2 & 3 are staying back not allowing their defence to poach.
4 &5 get all the space. Use the width and length of the feild to connect with your partner. Doesn't always have to be super fast movement.
Break throws are also great to get the movement across the field
6 & 7 wait intill their defence poaches or they see space that is open.
4 & 5 can always sub out with 6 & 7 if tired, or shout Vert.
