But should Dickson, a Quins Player before retirement, have been the referee for such a high profile match.
I have seen nothing to suggest that has ever been and issue for him, or any other ref. The job is a very difficult one to do, one that I do not envy. There are very few that make regular game changing misjudgments, but, hey, we are all human, and the rules say that the ref's decision is final. Unless they change their decision, which I have seen the better ones do. Indeed, THAT is probably the mark of an excellent ref, and when they do it with humour. The game moves incredibly fast, and it is all very well for thousands of spectators to watch, each with a slightly different view of the play, or the TV pundits with dozens of camera angles, slow motion replay and image zoom.
Running through their head is the question, is it important enough to stop the flow of the game? It is the same reason they 'coach' players. 'Leave it', 'Hands away', 'Stop' - you hear them all game. In an attempt to avoid infractions happening that would stop the game's flow. Nothing in the laws that says a ref cannot do this. Whether that tends to encourage an unwanted two way conversation is another issue. If the ref start talking to the players, they will tend to talk as well, so a talkative ref has the good sense to put up with this, to an extent.
Is Mr Dickson the best at this craft? I don't think he is, but he is getting wiser. Some bug (or used to) the heck out of me with lack of vision skills. Wayne Barnes with his 'I didn't see that,' or 'That didn't look high to me,' type of remarks. He used to miss some howlers, which tells me his eyes were pointing the wrong way, and he was in in the wrong place. A lack of game awareness, that many ex players would have. If you focus on where refs are in relation to the play and the ball, and what they are looking at, some are better than others. It has been most interesting to watch the Womens 6 Nations, and how much better at their craft the female referees seem to be at this.
Some referees simply don't have what it takes to be at the top level. I am sure we can think of a few that regularly 'get it wrong'. Karl Dickson is not in that group for me.
