A player stands on every cone from (2-7), the remainder line-up behind (1)
Player (1) passes to (2), then runs to join (2)
Player on (2) passes to (3), joins (3)
Once the ball reaches cone (4), next (1) can start.
Both balls continues to zig-zag down the line until one reaches the player on (7)
The player on (7) must return to (1) with the ball, but along the way, perform 2 x double plays with (5 & 3) respectively, before passing to next (1) without a ball.
(5 & 3) must be super-alert, as they receive balls from in-front AND behind.
Progress by using different types of passes from one of the lines (e.g. 2+4+6 use overhead/reverse shoulder pass)
