Yes, but the onfield ref is currently heavily influenced by VAR - you only need to look at the number of times the onfield ref has been called to the monitor and stuck with his initial call. It’s a miniscule percentage so if you think the VARs aren’t - practically at least - calling the decisions I think you’re mistaken. There needs to be a power shift. Last night appears to be a case in point - the VAR has now been stood down. The onfield ref, though, had the opportunity (and authority) to say ’thanks, yes, can see it bounce up onto his arm but I’m not giving that‘But what you describe is not what happens. The numptie says 'what do you think about this potential handball, O great on-field ref?', or simply decides that even though they think the referee's decision is wrong they won't ask them to check because the difference of opinion is not based on a clear and obvious error..
The only decisions called by VAR are offsides.
