We're drifting towards a philosophical debate about what is and isn't fair use of VAR here, which could go on forever without us agreeing! From my perspective, I'm not saying "delay a foul to gain control", I'm saying "delay a foul so that if you're wrong, you've not incorrectly denied a goal".My sense is that is going farther on delayed whistle than VAR envisions. It's one thing to delay on an ongoing GSO, but another to delay on a foul to gain control. That path, to me, seems a step to far and goes into the "let's just ref by VAR" model.
All I'm really saying is that you wait and see where the next kick goes. If it's cleared then you can either call it an advantage or give the foul regardless. Same for if the shot is taken and goes wide. It's only if it goes in, or is deflected out for a corner that you even need to act at all - and then all you're doing is giving the initial decision you were going to give anyway, and seeing if the VAR is OK with that call.
