Form evenly matched teams of 7 v 7 and play people in realistic positions.
(A) starts with a high kick to the top of the square, where 3 pairs compete.
Obey your structures, i.e. everyone shouldn't be flying for the ball.
If the attackers win it. they have a shot, if the defenders win it they attempt to go coast-to-coast.
Defender (E) starts opposite site of the ground to opponent (A), so the defending team should be aiming to use that player through the fat side.
If defenders can find (E), that player should run and bounce and gain yards, looking to draw (F)'s opponent.
Continue until attackers have a shot, or defenders shoot or turn the ball over.
Reset, substitute/rotate positions, restart.
