Quick Hands, you're ignoring the fact that the Australian broadcasters spend many times more on sport than the South African broadcasters. Super Rugby has limited appeal and showcases limited games in Australia. You only have to look at the deals the NRL and AFL, and even the A League have achieved to see how much more potential there is in the Australian market for Australian based competitions.
Currently South African broadcasters pay more for super rugby than Australian broadcasters do - but super rugby is more attractive in SA because all the games are on at a reasonable time. This reality makes it seem like we have no choice but to lock ourselves into a structure that doesn't allow rugby to grow in Australia.
But who knows where rugby could be now if after the 2003 world cup we had left super rugby and created an A League style (top tier) competition. I suspect that sort of competition would by now be worth a lot more to the ARU than super rugby is to them. But we'll never know.
The real hope now is that the NRC can be a big success despite being 3rd tier.
I'm not ignoring anything, I'm just dealing with the reality. I agree that for Australia an Aus/NZ Super 10 is the best option for us, but the reality is NZ have said that they would drop Australia before they would drop South Africa, South Africa want in, the ARU say that they the receive around 25% of their income from the SANZAR broadcast agreement and of that, 50% comes from Super Sport SA.
Pulver says going without SAF is not an option, NZ say they won't participate without SAF and the competition itself wouldn't exist without the contribution from Super Sport SA, so I think no matter what logic is applied, the argument is over before it starts.
As you say, we need 3T to become roughly the equivalent of Currie Cup and ITM Cup. What Super Sport have said in one of the articles that I've read is that they get all the derbies they want in Currie Cup, what they get out of super rugby is international competition. People in SAF want to watch Aussie and NZ teams, people in NZ want to play SAF teams.
