This make it even more important to go to the schoolboy level and build depth from there. Rugby is a culture, if you get a 6 year old in rugby, you'll get his family aswell.
Yeah, it doesn't really work that way mate. You blokes in South Africa would have a hard time understanding it because rugby is the only contact sport you play, but the reality is a lot of very promising players at the school boy level are likely to get scouted by any of our 16 NRL teams or their feeder clubs and offered contracts.
Increasingly this happens with AFL too - there was recently a story of a young kid in Newcastle who played school boy rugby and was a real star, but decided to play Australian Football once a contract was put in front of him by the Swans. And guess what? His family went with him...
Both these games have very very strong cultures, vast networks and extremely deep pockets. In fact, whilst the AFL is limited to Australia it has a higher annual revenue than ANY rugby union competition in the world anywhere, and the NRL isn't far behind, taking in a similar amount to the RFU despite servicing a much smaller market.
Union is actually very niche here in reality unfortunately. Heck, a test match against South Africa will usually struggle to pull a million viewers here, despite the boks being a big deal. To put that into context, a friday night football CLUB game of NRL ofter cracks a million viewers, whilst NSW v Qld rep games (Origin) will generally hit 4 million.
