Laws was in a position that was consistent with how the referee had applied the offside line all game.
He was not singled out to move back, the referee had observed Laws' position and was, one would consider due to lack of direction, content.
Forensic review will pick up many, many occurrences throughout the game where the decision could be considered marginal or even contrary to the facts as seen in super slow-mo.
The game is not played like that. Laws shuffled sideways, the ruck travelled forward marginally, the scrum half lifted the ball, happens many times in every game. If the tolerance line has been drawn by the ref, in real timed fully within his field of view, then that is where it should stay.
Another area of significant difference between show reffing recently has been the line outs; if the application of the laws in yesterday's game had been the same as the last few weeks, jumping across, interfering, taking the man out etc, then there would have been many more infringements pinged.
The game was what it was, the genie, TMO, is out of the bottle, trying to control that so as not to spoil the game is the extremely difficult part that will not please all of the people all of the time.
BTW - Last week, Farrell should have been a yellow and my thoughts, fwiw, England should not have won last week but should have won yesterday.
