I'm not sure if this is what you mean, but I like the idea of having a ref standing basically 5-10m beside the goalpost (opposite side to AR) to help call anything that happens in the box. If they think something should be pulled up, they raise their flag, otherwise play continues. It's an extra set of eyes from a different angle, it doesn't disrupt play, and if it improves decisions by even a small percentage, then happy days.
Nothing will ever be perfect. As someone else mentioned, the NRL are trying that and possibly making things worse every year. I was dragged along to some local league games a few years ago and it was great not seeing everything freeze for 5 minutes after a try - a team scored, ref pointed to the ground, half the crowd cheered immediately. They didn't need 230 camera angles to decide whether the guy's fingernail scraped the ball for "downward pressure" or any of that BS. Who wants football to become like that?
We got shafted with the Victory game when we possibly would have lost anyway. We got lucky against Adelaide. Swings & roundabouts.
