Im with jokin joe stalin and his merry bunch of bolsheviks. Footy zones are just awful to watch. Dull dull dull. Go back to the 90s and norf kicking long. They only had 2 subs and they didnt use them much. So 2 subs 20 rotations total. Enough to cover injuries but not fatigue. Also have the ump declare a zone is in play by the defensive team and allow special attacking rules during the zone play because zones will still happen. Allow forwards to block and push in the back during zone play but not defenders. So 18 defenders in a zone 16 attackers block a path for their full forward legally who can then push his opposite number out of they way. Thus making floods and zones ineffective.
