In an ideal world I agree, but the problem with the egos on these refs is that if the system was that the referee could only request help they probably wouldn't have the humility to admit they are unsure.
For me it's maybe time to get the automated offside system on board and for the rest maybe have a limited number of NFL style coaches challenges or something but that audio shows how absurd and chaotic it is to have 7 officials involved in each and every decision.
I don't think it would. The refs have always asked for help and now have more rules in place to deter player behaviour to goad them. They're currently losing control of games because they think VAR will bail them out. Giving them the power to review something if they want would then be a choice rather than demeaning them.
There is and always will be different interpretations of the rules. One person will say foul, the other a dive or "soft" for example. That happens up and down the country. But you're not in charge. The ref is and should be. So what he says is final.
Anything else like such as challenges etc still adds to something that can be so simple.
It's not surprising since VAR has come in the level of officiating has dropped massively and they've been binned off from major tournaments.
I remember you'd get probably about 5-6 awful errors by refs a season pre-var. Now it's one a week.
