I dont need to look at a failed UK model or USA movies
You just need to know that RL in Australia is district based and has been since 1908
Multiple attempts were made to run 2nd Grade and 3rd Grade comps
What you get is clubs who come and go constantly in these tiers. Thats why 2G and 3G were disbanded in the 1920s after trying that model for 20 to 30 years. We are seeing the same again.
Post Super League War brought it back and the Richo model you propose was tried from 2008. Then was dumped by over 50% of the NRL clubs within 10 years in favour of a return to the district professional development model
How can you possibly have an informed opinion if you refuse to learn about how other leagues and clubs have done things? And calling the the English football pyramid a failed model is just ignorance of the highest order. The EPL is one of the most successful leagues in the world and their pyramid structure has been copied (with modifications) by most of the other soccer leagues in Europe (i.e. all the most successful ones in the world).
Saying 'RL in Australia is district based and has been since 1908 is just a blatant appeal to tradition. Just because we have always done something one way doesn't mean that is the best way to do it, or that we should continue doing it that way simply because we've always done it that way.
Maybe it's just me, but I think the economic and media landscape has changed quite a bit since the 1920s, so who gives a f**k what they were doing a hundred years ago as it's got no bearing on today now that we have mass media and the internet.
Saying that the 'Richo model' was 'dumped by over 50% of the NRL clubs' is not only (egregious) cherry picking, but is meaningless as the fact that they don't do it doesn't mean it doesn't work.
Most of the grand finalists over the past decade (Roosters, Storm, Rabbitohs, Raiders, Sharks, Broncos, and Cowboys) are using what you call 'the Richo model', you wouldn't expect that if it was negatively effecting the club's development, and if anything if that is the model that the most successful clubs are using then maybe it should be looked into to have a better understanding of it's pros and cons. And I'll say it again, everybody with a brain agrees that Qld Cup model is more competitive and successful than the NSW Cup model, so why wouldn't you want to replicate that success as much as possible in NSW?
Finally clubs coming and going isn't an indictment on the system, it's an indictment on the stability of the competition. That usually means that it's too expensive for clubs to run in it sustainably, and that is a problem that a large successful organisation like NRL could fix if they had the will to do so.
