What happens if a player tries to catch the ball but knocks it on?
accepted OB,... but... there is nothing that prevents a player from kciking the ball fiorward, accidental kicks forward in a ruck that hit a team mate in front of the ball are notr (official blind eye/) called for accidental offisde, and there isn;t really anything that stops a s/h putting his feet inside a ruck (more official blind eyes?). Are you suggesting refs ping every s/h every time they dig out with a foot and the ball doesn;t come clear when the foot disengages, whether gone forward or back.
That's not to say the point you make isn't valid in itself, just that I do not believe the analogy is valid. As refs you must decide whether you will permit s/h feet in the ruck or not, and accept the consequences of allowing/disallowing that or I suggest WADR you are introducing too many grey areas (where the laws arguably require you to have to make far too many of these already, as oft debated here)
"Yes, you can put your foot in the ruck s/h but
* the ball must come out 1st time
* the ball can only go backwards
* you can only do it once cos otherwise it looks a deliberate policy
* but I may allow you a foot movement to give you better hand access
* maybe"
I suppose the s/h could always bind, kick it forwards then unbind of course.
And what would the difference be?
W/out meaning to be ornery, it seems a pedantic area to get into when you as refs have enough already to concern yourself with. Especially given the amount of times it is likely to happen in a season, let alone a game.
