Sorry, but you can't have any meaningful discussion about youth rugby in this country until you tell the various schools associations that they need to open the gates and establish a wider base
In order to combat the school strangle hold, you need an attractive alternative. The state championships is a dead duck essentially after about the U14's with school kids pulling the pin left right and centre. Can the state champs at this point, reload that pathway into a "semi professional" system like the NRC, All state and ARU funding for the state champs goes into the NRC system, and the parent funding of the gold cup (currently $600 per person), funds the running of the NRC style comps. There is absolutely a chance it could occur.
I can tell you know, kids who sit on the border line of league and union at about age 15/16/17 will swing to league 90% of the time due simply to the fact they are training with the senior guys, faces they see on TV and the bright lights league makes are very deceiving to a kid. If union doesn't try and create a pathway to mirror this, they will lose every day of the week.
The most successful Gold Cup teams have been from Melbourne & Perth, a single team city, NSW & QLD are spread to thin, need to combine these into 3 or 4 teams to align with the NRC and create a really solid stable competition accross the board.
Would be easy as piss to organise and administer, you would quite literally only need half a brain cell and one bloke at ARU level to administer it, not to mention the freed up resources at club level and so on.
The other advantage to this system is that the clubs then need to come to the party and assist the NRC teams in order to get their mits on the young talent coming through, rather than one particular team building a super junior rep side and killing everyone, while the rest suffer.
It could run cost neutral at the very least in its first year, and would be alot more attractive to sponsors if they have a wider market reach!!!!!
