And there absolutely is. Bring in a clear and obvious aspect to VAR too, as you mentioned earlier.
Just because the PL might have technology to judge an offside to the nearest mm (and even that is exceptionally arguable, to be honest), doesn't mean they have to use it. They can use VAR however they want to use VAR. They choose not to use VAR for second yellow cards. They choose not to use VAR for throw-ins. They don't have to use VAR to judge an offside decision to the absolute margin. They are choosing to, but they can - and they should - change their mind.
Ditch the lines. Have a look a replay. Maybe two replays. If the decision from the linesman is clearly wrong, then overturn. If not, then stick with it.
I'm not going to get too worked up about it now, because we're in season one. As I've said before, I fully expect it to take at least three years to perfect VAR. So I'm very open to issues arising along the way (and it is right to highlight them). I would envisage changes being made every season. But if in, say, five years time I'm still seeing us waiting around two minutes whilst VAR tries to work out if an armpit is offside or not, then I won't be a happy bunny.
