Quite often you see players penalised 50m because the player has clearly played on so the other has reacted, but the umpire simply hasn't technically had the opportunity to call play on. Is that a good look for the game?
There is no "technically" about it. It's a discreet black and white act.
And will only be made worse with this new rule (which I like btw).
It will be made unambiguous by the new rule
And it has a simple solution which has proven to work in other Sports, which doesn't change the fabric of the game at all.
You haven't made that case at all.
1) Australian football is a much faster game than soccer or rugby union and has three umpires. The advantage rule is not "simply" transferable.
2) There is no analogous situation in either of those sports to the "man on the mark" situation in Australian football. Soccer has a dead-ball free kick. In rugby a conversion kick the opposition can break once the player starts moving. In Australian football it is very grey as to when a player has ran off the line of the mark sufficiently enough to be called play-on.
