Thing is, even the sports that have the tech always end up moaning about the decisions, just adds another layer of blame to the situation – keep it real time and accept that mistakes will happen, it’s all part of it…..
It works very well in cricket with the umpires making a decision on the ground and the players having to appeal if they think its wrong with a very limited number of appeals – the tv replay umpire then has to find evidence to overturn the call on the field. If its inconclusive then it goes with whatever decision was made live. It has led to more correct decisions
In rugby union I don’t think they have it right as they cannot examine anything but the act of scoring but I like the two questions aspect, league is better in that the replay ref can look at more the live ref will ask them to look at specific things in the run up to the score as well such as offsides.
However I really am not sure if it would work in soccer – maybe for over the line or not but not for anything else or every goal would have to be looked at in detail
I am not sure for football
