The pace of the game at academy level, to nl1 to championship then to SL changes nassivoy at each step. So a number if factors cone into play, mainly time! Time to get in the right position is one thing and the other is time available to see what's happened and make the call.
I can't agree with you saying in the game we have persistent offside, or persistent not square at the ptb. I don't think teams get away with obstruction either. Forward pass is again interesting the momentum rule seems to cause confusion, but pure physics means a ball leaving the hands in a backward motion from someone travelling at pace fwd will actually travel fwd but it's not a fwd pass.
The ptb, yes I agree and it infuriates me that we are where we are, but the difference between rolling the ball, back and not using the foot and putting it I the floor and stepping over it us very different, I don't think the second one actually happens that often.
The reality is, and you will never be able to change this, is, if you could go back in time and just replace the match officials in a game that us played you will always get different decisions and outcomes. Why? Not because of inconsistency in the application of the laws but because for the exact same event one ref might be in a different position by say two feet, he may have just looked to his left rather than his right. So taking the example of the Harrison tackle, let's say it was exactly the same, same part if field same lifting action same manner tackle was complete. Why would 2 different refs cone to the view one deserved further action and the other not. Because they saw it differently, ref in Sunday might have been 3 feet closer or further away, he may have just been distracted by Willy barthue talking to him, etc etc but on the day at that moment in time each ref called it as they saw it, you can't change that, it will always happen.
I know the training and preparation that the full time refs do, trust me getting more in would not be easy, as fit the part time guys just like the players at that person that all have day jobs as well.
As a sport we need to get back to where we were. RU can still manage it why can't we
