The BIG difference between AFL and Rugby!

From a Physio perspective in Victoria there is a MASSIVE difference in the way footy players are nurtured compared to Rugby players. You can see it in young kids as early as 5yo when they're in programs like AusKick. From Auskick young footballers are educated at their local community club and school by their members, parents and footy leagues (all the the overarching support of AFL). Rugby players (I've observed) do not have the same structure and support and you see it as the athletes reach 12-14yo. Around this time when they are approaching high school, footy players really start to hit their stride. They understand good nutrition, recovery measures and have a great sense of playing footy. Rugby players start to breakdown quite badly in this age group... I wonder what the differences are? Grassroots? Corporate vs Community?
