Wembley is going to look pretty empty regardless of any boycott. Also, people have short memories, so this will all have blown over by next week.
There should be more respect for officials and a proper and strong no tolerance policy introduced for back chat and the like. That said it is not surprising that fans and players get frustrated by wrong decisions and the lack of any acknowledgement from the RFL that they are wrong. There will always be mistakes when under pressure, especially in a high speed game, and this should be respected but why can't such mistakes at least be admitted or acknowledged? Maybe it would be cold comfort after the event, but better than just having to accept it without question. Referees and the head of referees should be far more accountable and far more open which ought to give fans and players a much better insight into how and why decisions are taken, and ought to lead to an improvement in standards.
For example, most people thought there was a spear tackle yesterday, but the ref didn't give it. So why can't this be explained? Did he not see it clearly it? Did he see it differently? Would he have changed his decision with the benefit of hindisght seeing it again? I'm not suggesting every minor decision is scrutinsed just what appear to be the major ones. Just a bit of explanation, even to see say he got it wrong would make us and the players respect them far far more.
