If what you say is right, and I do agree with much of it , Wouldn't we, currently, be better of making as much money as possible? pumping that money into the existing grassroots and shoring up what we already have? not investing hundreds of millions in new sides that are not going to see any return on for over 10 years !
The only way to make as much money as possible is to seek national coverage as soon as it's feasible, and there's no way for the grassroots outside of NSW and QLD to grow beyond their current standing without a path to professionalism. In other words if we don't expand we're stuck.
The NRL is already committed to spend a hundred million on each club over ten years through grants, so getting upset at the prospect of the NRL propping up expansion clubs to the tune of hundreds of millions of dollars seems pretty stupid to me when they are already doing it for the rest of the competition. At least if they were spending it on expansion clubs the money would be being spent for a purpose other than just to prop up clubs that can't support themselves...
Also considering that NRL clubs are significantly cheaper to run than AFL clubs, if the NRL can get a deal similar to what the AFL got for their last round of expansion, then expansion shouldn't hit the NRL's coffers to much at all and could even be profitable.
The NRL has another advantage that the AFL didn't have when they last expanded: Demand for teams. There're are people all over the country that want to pay the NRL for the right to bankroll a team, as long as the NRL does their due diligence they should be able to find at least a few that would be able to basically self fund themselves (minus the cost of their annual grants of course).
So basically, assuming they don't f**k it up, expansion shouldn't have a huge impact on the NRL's funds.
Finally, we already have/had the resources to start fighting back in the grassroots of NSW and QLD, but we took that money and now we're using it to fund the NRL's clubs ridiculous $13 mil annual grants that the NRL can't afford.
