Basic setup after bricked pull/disc centralised. 1: Mark: Forcing towards nearest line. Priority is to prevent break throw to Red 3. 2,3,4: Wall blocking any forward pass. Marking any threat around/behind their space. Note wall is slightly more towards the open side of the pitch. As no clear threat on break side and this is 1's responsibility. 5: Deep: covering any deep shot
As offence players cut in wall marks any threat.
Only 'easy' option should be for swing to open side (to red 2) 1 follows disc. Priority is disc does not go back to Red 1 or 3.
Zone constricts as disc gets closer to sideline. 1: Moves to mark the around/backwards dump. 2: Moves closer to disc to block IO swing 3 and 4 aware of any crash threats or line passes. Short crashes can be tolerated particularly if disc rests with weaker thrower. Zone most keep shape and limit impact of minimal gain throws.
