Fristly it seems to me to be self-evident that continuing the same path is ultimately ruinous to Australian rugby. But yes, agree we dont leave if staying works.
Currently the well-broadcast requirement of NZ to continue with SA is something we should be surprised by. And the SARU requirements are very likely imo to be not just more of the same but getting worse. Both positions quite well broadcast.
And if we are not offered something that works for us then we need an alternative and we need to have the courage of our convictions.
I dont agree with your assessment that somehow SANZAAR would become commercially vindictive. Its a commercial proposition that stacks or doesnt.
Otoh I CAN see SARU doing the sleight of hand on revenue being attributed to Currie Cup, not Super Rugby. and that is behaviour that is impacting us right now.
You've said that SARU and NZRU are getting everything they want at the expense of the ARU and then said that you can't see them becoming commercially vindictive if we walked from SANZAAR. I don't see how those two positions mesh. The SANZAAR agreement covers both Super Rugby and the Rugby Championship. If we walk away we would have to start negotiations all over again and that would include playing test matches against the other three countries during that period.
Clearly NZRU has made it clear that playing South African teams is a key criteria for them. Super Rugby is changing and that number of games is decreasing. They now only play three South African teams each year. As our position on the viability and success of Super Rugby is changing, the same could quite easily be happening for New Zealand.
To my knowledge, SARU getting a higher share of the revenue by splitting out the Currie Cup revenue and assigning a higher proportion of value to that was a feature of the previous deal. In the 2016 deal that disappeared which was one of the reasons our share went up substantially.
