People go on about how VAR kills the joy of a goal - and it does - but that would be a price worth paying if VAR was certain to get decisions right. It isn't. It interferes in things it has no business interfering in, is as inconsistent as any human official refereeing a game, and brings in toenail offsides that the human eye either called reflexively or missed completely when linesmen were responsible for flagging (allowing us to either blame the lino or excuse him on the basis that judging offside is impossible for the human eye).
Scoring a goal is difficult - as DCL can testify. VAR gives the impresson of doing everything it can to find a reason - often spurious - to disallow a goal. "His knee is offside", "he touched him", and other such ridiculousness destroys the benefits of technology. Having a shoulder or a kneecap beyond the last man would result in a flag or no flag in the past. Now it results almost certainly in a flag - but also a three-minute delay. And for what? In the spirit of the rules of the game, a shoulder or knee was not why offside was necessary. It was to stop goal hanging.
Football was always a contact sport. "Touching" somebody before playing the ball - or even after it as happened at the World Cup when Szesze...Szeszeny...the Polish goalkeeper dealt with a cross and grazed Messi with his hand as he fell for the concession of a preposterous penalty - was always part of the game. Force is what used to be taken into account, recklessness, or endangering an opponent. Or simply gaining a premeditated advantage by making contact with a player. In this case, the keeper didn't even see the beatified Lionel, dealt with the danger, and unknowingly feathered the Argentinian as he fell...only to be penalised. A farce. You just know Beto isn't getting that penalty.
Technology itself can be managed. But it needs to have very clear and specific applications. Allow coaches to call for VAR no more than twice a game for offside or penalty incidents. One issue right now is the feeling - paranoid or not - that VAR is used to benefit the fashionable sides. Reduce that by allowing each team two reviews. Allow the video refs to call the on-field ref to a screen ONLY when an egregious error has been made (an off-the-ball incident, for example, or when clear daylight can be identified between the forward and last defender in an offside call). VAR should not be "looking at" or "checking" every single incident in a game. Human error is priced in to the game. If you introduce VAR with all its constraints, you HAVE to eliminate it or it becomes bureaucracy. And that's always the first step to dystopia.
