Oh don't get me wrong it's definitely a fair debate, however the people that are steering the debate are the wrong people to be doing it... When e.g. Wayne Bennett, Craig Bellamy, Phil Gould, even your Buzz Rothfield's, etc, etc, suggest that the VR (I hate calling it the Bunker it's so corny and gimmicky) shouldn't be able to adjudicate on whether or not a e.g. pass was forward they aren't doing that cause of any real reason that they think that the bunker shouldn't be able to adjudicate on it, they are doing it cause they see that the bunker not being able to pull up a forward pass is an advantage to their teams that out weighs the disadvantages.
My opinion on the subject would be that the bunker should be able to adjudicate on anything that the technology allows them to do without severely impacting the game or the flow of the game, i.e. if the technology exists so that the VR can instantly adjudicate on a e.g. forward pass then they should be able to do that (which btw it does but it's not used in the NRL), however if that technology doesn't exist and/or the play has moved on since the mistake has been identified then it should be ignored and play should continue.
I personally don't care how a team is pulled up for breaking the rules, as long as they are pulled up and it doesn't fundamentally change the flow of the game, but that is just my opinion.
