The elephant in the room is the legality of the salary cap itself. The argument that the whole damn thing is unlawful is legally pretty strong.
The NRL probably don't think we will go down that path because we are one of the "poorer" clubs that the salary cap is intended to protect.
But if we are subject to more stringent rules than others while the NRL's darlings get away with murder, what have we got to lose? It's not a level playing field anyway.
I'd be going full bore with that argument. I would also suggest to the NRL that our lawyers want to launch a class action on behalf of the players who have lost millions in income due to the NRL's unlawful conduct.
In short, I think we should go nuclear.
The problem is, should the salary cap be found unlawful, there could be multiple consequences for the NRL.
For a start, every club fined for a breach has a compensation claim against the NRL administration for fines paid, players moved on to be compliant and damage to reputation. The Storm would sue to have all their premierships re-instated and doesn'tmatta, dogs and worriers over their point losses.
Then there is the issue of ending up like European soccer leagues where a handful of teams in each comp effectively dominate almost everything, should a legal and suitable alternative not be found. Do you want to watch a top 4 of souths, brisbane, roosters, storm or dogs every year, probably not. These clubs are probably wealthier then they have ever been.
The end result being a comp that becomes boring, and we don't have a culture of supporting our teams best result avoiding relegation like english soccer fans, expect for the rare fairy tale (i.e. Leicester city).
The issue is not the concept of the salary cap, most sports have caps on spending in an attempt for parity, even glamour sports like F1. The issue is the current salary cap system allows for systematic abuse by wealthy clubs with large TPAs or non-player expenditure to give them a competitive advantage. It needs to change, with the most popular suggestion being player salaries becoming public knowledge (although there is privacy issues there).
Second to this is a comp that spreads revenue and a supporter base across 9 teams within 100kms of each other while other clubs get a whole city/region to themselves. 2 Sydney clubs need to be moved to Perth and Brisbane (to break the monopoly of Brisbane). Letting souths back in hasn't helped either. It is a tough thing to do to fans but it needs to be done. It will hurt in the short term but will improve the remaining clubs in the long run.
Finally, and most importantly, you have an incompetent NRL administration that clearly favour select "pride of the league" clubs. They can see clubs like donkeys, chooks are abusing the cap, but wont dare touch them. They are running the game into the ground while the fans scream at them for changes (e.g. 1 referee).
Anyway that is how I see it.
