This is just stupid, where do you draw the line? 5cm, 10cm or 30cm? Then we would be back arguing about the same thing again.
No, it is definitely not stupid. It is by far the most sensible way to use VAR for offside decisions seeing that VAR objectively cannot make accurate judgements due to limitations in frame rates. There 100% has to be a "referee's call" margin for error applied just like they do in cricket with LBWs and Hawkeye.
That frame rate thing has been debunked and it was completely made up by Daily Mail. Games are broadcast at 50 frames per second but the cameras VAR use go up to 300 frames per second IIRC.
I can't find evidence of the debunking.
First reply.
There absolutely needs to be a margin for error on the basis that it's impossible to tell exactly when the ball has left the foot of the player passing the ball, unless they have Ultra HD cameras running at whatever the necessary FPS zoomed in at the feet of every player on the pitch.
