All the more reason to give him the option of asking for help, then, and there's no better argument for it. Just like with goal-line technology — the idea of which was also opposed for years, as I recall — if everyone can see the decision is correct, then there is no blame game to be played. If the question he asks can't be resolved straight away by the video ref, then it can't be resolved, and there will be a default decision. We'll all know in a few tens of seconds at most (in the majority of cases, much quicker than that), people can see that the best attempt at fairness has been made, the issue of blame doesn't even arise, and the authority of the referee is undiminished. The opposite, in other words, of the situation you're lamenting, which is what we have to put up with now. The idea that huge amounts of time would be eaten up with this is an absurd straw man. How often are we still waiting for a decision these mythical weeks later in rugby, where there are usually far more technicalities to consider and bodies in the way?
