Step 1

The offence sets up In their stack. The defence is playing person/ man on man defence. Except #1 and #2 are sharing their players. #1 is deep of their person and #2 is positioned under in the throwing lane, this way they can help block the throw if an offensive player runs to that space.

Step 2

In this case if Blue #1 attacks under then #2 red will defend them. This blocks off the passing lane. In this scenario #1 red should move forward and not be so far behind the deepest offensive player.

Step 3

This forces offence to reset their stack.

Step 4

Another scenario is #2 blue attacks under and #1 blue goes deep. In this case the defenders each stay and protect their space.

Step 5

And if the offensive players switch directions, the defenders don't chase and instead "share" their players with their teammate.
