YepTrouble is VAR isn’t accurate enough to make these calls. 2 frames on and the ball is still in contact with the player’s boot as he passes it and the attacker is onside.
The accuracy of this system is dependent on 2 key things:
1. Which frame the operator decides to freeze.
2. Where the operator decides to draw his lines.
The system is therefore defined by the frames per second of the video, and the resolution of the still frame - none of which are that detailed.
The huge flaw is that pick a frame or so on, and the offside lines give you onside. This isn’t accuracy, it’s the guesswork of the operator of what frame they pick.
Personally I think the assistant referee made an excellent onfield call, his positioning is immaculate and with the human eye he couldn’t have made a better call.
But VAR, inaccurate itself as described above overrules a perfectly good decision.
It’s a disgrace that it’s been adopted in a way that says it’s infallible - we can all see it is.
