Here's my number one concern with VAR and it's something that is being proven quite often.
- On-field referee knows that there's a back up if he makes a wrong decision, therefore is hesitant to give red cards, offsides and penalties. This influences his decision making and nowadays we rarely see big calls made on-field. If someone goes down in the box, the referee in 9 out of 10 cases waves play on because he knows VAR will check it.
- VAR now not only have to check for a red card or penalty, but they have to do so keeping in mind that the on-field referee has made a decision and whether or not it's a "clear and obvious" error.
This leaves you with a situation where the first decision is a 50/50 because there's no conviction or bottle to get a big call wrong, knowing that someone else can check it. Followed by VAR having to work out if a 50/50 decision isn't necessarily correct, but if it's incorrect enough to overturn it.
Whichever call the ref made against Trafford, VAR would not have flipped the decision. The referees are making call after call with VAR in mind, that's what is wrong.
The referee in a sense didn't make a call at all. He didn't signal anything - he didn't point upfield to the centre circle, he didn't signal free kick. He just stood there briefly, and then ambled back towards the middle of the field. The Luton players didn't pile into a heap near the corner flag as they normally would having scored a last minute goal, they stood around and looked at the referee before realising that he hadn't disallowed it.
VAR has just been on ref watch. The ref thought that Adebayo didn't move into Trafford and it was Trafford who barged Adebayo, which is clearly factually wrong. Adebayo moved into Trafford. That in itself is enough to tell the ref to take another look, because what the ref thinks he saw is not what actually happened. Bankes, VAR man, is inclined to think it's a foul but not enough to overturn, not clear and obvious. The assistant VAR man, whoever he may be, is convinced it's a foul and the ref ought to be told to look at the screen, but Bankes overrules him on the basis that the goalkeeper is allowed to jump and use his hands. (No explanation of whatever law makes that relevant.)
This idea of refereeing by committee is a shambles. Total shambles. In rugby league, the ref is in charge, the linesmen are there to help, the VAR man will only butt in if he is asked, the players have to keep their distance and accept the ref is the boss. Basically, the ref is the man in charge, and it works.
In football, the ref has the VAR man looking over his shoulder, PGMOL sitting on his other shoulder marking his every decision three or four times per minute, two linesmen rabbiting in his ear (and some of the never shut up, even in lower leagues), and the players having almost carte blanche to swear and shout and interfere. They're trying to referee a match by committee, and it doesn't work at all.
