The damage now is irreparable. You know the idea of "dare not speak its name"... despite all the outside pressure, the NRL had better not said anything about concussions, other than discretely with the players union and the club.
Instead it blurted all this nonsense out, and now you cannot walk back any of it. How can you?
Because as much as I think the 6 again rule is largely responsible for the blowouts, the thing that has sealed it is the heavy handed "player protection" crackdown. And I'm not just talking about high tackle sin-bins and send offs. I'm talking about something that has only gotten worse from an already bad position years back, the increasingly soft interpretation of a "crusher" tackle.
It's already hard enough for retreating defenses to cope after repeated 6 agains, but then they are having to be extremely cautious with their defense. They can no longer try to put a sting in to their tackles, because accuracy over force is the imperative.
Further... I feel that refereeing inconsistency is a huge factor too. I know it's always inherent, but it's magnified by these rule changes/dulling down of the game.
All of this cannot be walked back. We'll all probably adapt to continue watching, out of habit... but it's a meaningless game now.
