Nice Try! I understand the rule and she breaks it. If her foot is off the ground while the kicker's is still behind her, she is not fulfilling the rules. But, yes, I'm old enough to have seen the Russian Linesman live!
EDIT I see I have MISINTERPRETED "in line" as "on line", in which case, it is certainly difficult to tell from front or back whether Earps's foot was "above" the line as opposed to being "on" it, which it certainly wasn't. If it was above, but in line, that would be ok. But consider ye this from The Roolz:-
Once the ball has been kicked, the goalie may dive slightly forwards as they plunge to either side and this can help narrow the angle.
She is well in front of the line by the time the ball is kicked. I have to admit that my case is not helped by the fact that VAR did not query it and the Spanish players did not protest. But I think that makes all of them wrong, too. Truth is not a democracy!
Have another look - is she moving forward before the ball is kicked? And does it matter? Please keep your answers brief and on one side of the screen only.
