Disagree.
The rules are not that different to years ago. Yes, a few changes, most of which should just be reversed as they make it more complicated.
The problem is the inconsistency in adjudication. I will try and find it, but I distinctly remember a short passage of play, maybe 1974 Grand Final, where one player grabs his opponent, just for a second, and then lets go, as they pursue a bouncing ball. It is paid holding the man, as it should be, and Lou Richards commentating says, well, he grabbed the other player when not in possession. The issue of congestion is exacerbated by the way players are grabbed before they even have the ball, and as a result have no chance to dispose of the ball once they get it. You can push (not in the back although that is often overlooked) and shove when your opponent is not in possession of the ball, but any action where your hand actually grabs a player or their jumper is holding the man. Pay it every time and it will stop happening. Don't pay it every time and professional footballers, backed up by coaching and club staff who analyse games, will see how far they can push it. You end up wit the mess we now have.
Make the rules simpler, which actually won't mean many changes, and enforce them every single time. Yes, there will be more free kicks, but there will also be more consistency and behaviour will change. Plus, more free kicks means each individual free kick is less important to the overall game. When they are paying only 30-40 free kicks a game, each free kick takes on more importance.
