How? Think that’s a great idea tbh. Should have been the law from the start.
so at attacker could be at full pelt with the defender moving up to play him off, if his trailing leg during the sprinting motion is in line with the defender he's onside?
sounds worse than now tbh
It'll be just as bad, stupid fucking lines being drawn etc.
Do it like the Dutch if you have to have VAR. Thick lines, and if the lines touch, then go with whatever the original call was. Makes sure it's closer to clear and obvious that it was originally being touted for.
Also, get rid of VAR for keepers off their lines. They've literally got an official watching just that. If he can't call it, then let the keeper off.
While we're at it, get rid VAR all together actually.
