However its done, Offside is still a binary thing - it is either offside or not offside and someone will still be called offside by "a toenail".
So the moaning will not cease - unless, football introduces the equivalent of "umpire's call". But for that, the ARs will have to make the "call" (as opposed to today's "wait and see" protocols" and - as long as it is within an agreed tolerance level- what they say goes. It does mean that you could have two identical scenarios with one called offside and the other not, but that is what happens in cricket and they sort of accept that. Might be a bit of a stretch for football though?
Agree totally. This will change nothing. Even if you say a player has to be two yards offside to be penalised, the 'pundits' will then start kicking off about the ones that are two yards and half an inch. It matters precious little where you draw the line, it's the perception of it that needs to change. The sooner everyone just accepts that some marginal calls will go for you and some against then these pointless conversations will stop.
Personally, I've always thought a far easier way of judging offside (and selling the decisions to the masses) would be just to use position of the feet.
