Surely by now we know the rules:The Johnson Rule only ever applied to MJ;Pav has his own private 'insufficient force' level so it's anyone's guess.
The Collingwood rule for fair fixturing
The Fremantle only rule for finals venues.
The Pav rule for insufficient force. (Judd)
Umpires being permitted to mark the ball.
The sirengate rule.
and the very latest The Fyfe rule.
Probably missed sum but these are the rules we play by.
