Huge points above, thanks Bb. Note all Aus posters extolling the seemingly hallowed benefits of our salary cap: RSA rugby now has 2-3 consistently strong top S15 teams who have won multiple and many S1x titles. Sorry there's 2 weaker clubs but the harsh fact of capitalist life is that an emergent hierarchy of success over less success inevitably happens over time due to combinations of money and talent. But the obvious derived benefit is strength in depth over time, vs weakness in depth. I am not arguing that salary freedom is the reason the RSA S15 team situation is as it is, but it manifestly helps that top teams can hold their best players and further create virtuous, quality-consolidating circles whereby their relative commercial success can permit them to bid to gain the best up and coming players from all over RSA, as well and combine these players with their existing top players. So the strong will get stronger this way, but that is exactly what's required to consistently compete with other top RSA teams and other non-RSA top teams. The right goal of the best managed teams is consistency of victories, not a once every decade (at best) affair. Then, having consolidated 2-3 consistently top teams, media and fan interest consolidates too, sponsorship and media $s grow, and the whole code thus gets healthier over time.
But sadly many posters here are comforted by the unproven notion that by a quasi unionist-socialist model of central code player cost control, in 10 long years time we might have 5 franchises that are all about at each other's standards of achievement (though no one quite knows what that levelled-out standard will be).
