Setup
Form 2 evenly matched teams of 10-14 players each. Split on-ballers, forwards and defenders between the teams. Give one team a 5-point lead and possession from a kick-in (yellow in this instance). Choose between 1-3 minutes remaining - obviously the longer the time, the more likely a score. Tell players the situation they're in, and challenge them to set-up accordingly.
Step 1
Coach calls out the remaining time left to play - 2 minutes is about the norm - and starts the countdown timer. Team (A - yellow) have possession and must starve (B) of a scoring opportunity. Team (B - red) must win the ball back, but also can't afford to let (A) score again, as the match will be effectively out of reach.
Take note of the way players instinctively set-up without instruction
Start the contest and watch it unfold, then discuss their chosen formations.
Step 2
Team (A) have 2 choices - the first and most preferable in dry conditions is to play short to retain possession.
If (A) choose to retain possession, your dead-eye kicks must be the only ones leading in the vicinity. Hit as many short leads as possible to get the ball over the 50m arc, thereby avoid bombing to a 50-50
(A) should play around the boundary, not in the corridor unless a player is all alone. Once everyone is covered short directly ahead, look sideways and behind for options - it's okay to go backwards and sideways to find free players and chew up more clock.
This is of course rarely an option considered in very wet weather.
Step 3
Team (A)'s second choice, is to kick the ball long. They'll have to do this when everyone short is covered. In doing so, hug the boundary as much as possible.
Team (A) should get as many bodies around the dropzone as possible, to, at minimum, cause a stoppage.
The proximity to the boundary reduces attacking space for the opposition
Cover the opposition lurking free through the corridor
Step 4
Team (B) need to win the ball back, so push everyone up and form a zone defence.
Once the long kick is executed, a great strategy to make something happen is for a tall to punch the ball forward - it can easily end up in the hands of a loose red who can set-up a score.
Above all, team (B) can't let their opponent chew up easy clock. They must create a rolling zone to cover space after every kick, alert one another of approaching players, and force (A) to kick to a contest.
If possession is gained, look to switch to use the open space rather than bomb back into congestion.
Step 5
Play out the match. You'll need to umpire and stop the timer for stoppages for shorter games, if you can manage.
If either team scores (a goal OR behind), the other team get possession from a kick-in at the same end (no centre bounce).
Obviously the strategy of teams will reverse is there is a lead change, so players must quickly get into a different mindset.
Step 6
In consecutive turns, start from different positions on the field such as the back flank/pocket.
