The shape
The AFL 9s (3-3-3 zones) sets out 3 in backs, 3 in centre line and 3 in forwards. The diagram shows where each position starts, on a 100 m by 50 m australian rules football field drawn to scale with your own end at the top. Use it as the starting picture for your team sheet, then adjust the depth of each line to the players you have and the opponent in front of you.
