VAR Isn’t bad for Football
I personally think it needs to be more optimized. It’s still a new tool, and like all new tools it’s unlikely to work perfectly at the first go.
For example, handball rules were recently changed. With VAR, at slow speed, every time the ball touched a hand it looked deliberate, hence the definition of handball “deliberately handle the ball with hands” was failing. Referees can’t read minds, so whether a touch with the hand was deliberate or not is much a matter of judgment. This pushed players to always shoot at hand height, since there is no way defenders could get them out of the way when fired at from a yard away. So, now it’s a handball only if it makes the defender body bigger, or it’s above shoulder height. This already makes more sense.
Another thing that needs to be optimized is when VAR should intervene. The referee is unlikely to decide on his or her own to take a look, and people seem to distrust referees off the field making a call. Several coaches have complained that they don’t know who is in charge.
If this issues can be rectified, VAR would be a very efficient tool. Another thing that is much better is that goals resulting from a clear foul are no longer allowed. For instance, Maradona wouldn’t be able to win a world cup match by scoring with his hand.
Overall, I think VAR will improve the game, but it will take time and optimization.
