Can you please clarify? I can't immediately picture anything other than a KO advantage, i.e. where the ball has got into the possession of the opponent anyway, that allows t/o without play being having to be stopped?
the suggestion is a Law change, so that a knock-on is no-longer an offence.
I also am interested in that idea, and I'd love to see an ELV trial.
(NB a throw forward would still be an offence, as would a deliberate knock on)
