If it goes to the vid ref the vid ref should take one look and if he can't decide one way or the other it should go back to the refs decision.
It's all the p1551ng about with the replays that gets me.
If you can't decide in the first slow mo then the original refs decision (good or bad) should stand.
We're trying to make it perfect.
Life's not perfect, sport should reflect life.
That's what makes it interesting.
