Countervailing that protocol is the practical desire to keep the game flowing and not stop play for every "close call" that arises.
Before VAR that was deemed inevitable, and that in keeping the game flowing, there would be mistakes that occurred, because the officials are only human!
However now we have VAR,
every close call which can influence the outcome of a game, must be investigated; actions
in the box that could lead to a penalty, a red card situation, etc. and of course offside issues. This should happen no matter how many 'close calls' there are, even if one arises every five minutes and it takes two hours to finish the game.
Surely we cannot say "we now have the technology, but only use it when we feel like it".... every silver lining has a cloud!
