You've missed the point, just as the ARU missed the point year on year. The systems are shit. yes, but your attitude accepts that it is beyond fixing. If that is the case just give up. F^%$ managing expectations. Play to win or don't bother. That means accepting that you may well lose but at least seek to improve skills and application.
No use bringing up the Bok, they like France are hamstrung by their own structural issues. The Pumas likewise. England is finally getting their shit together and Wales would beat the Wallabies far more often if they had a coach that had some semblance of an idea of what to do.
Being professional has been lost to a large degree in Australia across many professions because far too many people obtain a position and a bit of paper and they have "achieved" professionalism. They then become stagnant apart from expanding their paper portfolio. No skill development from then on. Name me a Wallaby back that is better today than they were when they debuted for the Wallabies.
I do not accept that our Pro players have less potential than AB players. In fact there are some individuals like Folau and a few others that have a greater potential, achieving that potential take decent coaching and application by the players.
