Whatever offside rule you make there will be a point where it switches from being onside to offside. Around this point there will always be arguments.
Of course. I agree. I am assuming that the repeated comments on here and in real life dating back to before VAR that an offside call when only a nose hair was offside is against the spirit of the game. Given that VAR will allow a very precise estimate of whether it is offside or not, why not make everone feel a bit better about the outcome by making it a bit less harsh on the attacker.
And it is worth noting that exactly the same applies to goal line technology - it is either a goal or not, down to almost angstrom precision, and yet everyone is comfortable with goal line technology.
Clear blue dayliht on offside won't make VAR any quicker but it will result in less ire.
Until Zaha is ruled onside when he scores the winner against us with his silly arse cheeks blocking out the clear blue daylight, of course.
