They should have two officials in the bunker. I think it was a financial 'corona' step to have one, as well as some other problems with two officials. So to fix that problem which was, they did not have a clear posttion of leader, what roles to play each bunker offical does. So one official can constantly be trawling past tackles while the other is engaged on current play. Counter views on tries would be helpful. Also greater examination of captains challenge. Most times a challege is set upstairs as a simple inquiry, but other rules were broken , which is not looked at or adjudicated on.
