I'm concerned with the situation of state v state, mate v mate. The very reason SOO came about.
SOO the ultimate contest founded by state rivalry when previously NSW picked QLD players when they joined NSWRL, to play against Qld resident State sides.
That whole premise, that drives the rivalry and the greater passion in Qld for SOO tribal revenge, would be lost, or watered down, if players who don't want to go on and play for Australia are made eligible.
There's rivalry of even how many players each state get picked for the Kangaroos, based on which state wins the 3 game contest. That would be gone as well.
As a hypothetical....You could have the situation where JT plays lock for QLD.
SBW plays lock for NSW.
The Australian Kangaroos are picked and neither player commits to the Australian team and you're scratching around looking for a guy good enough, who will play for us.
All the while the press rabbiting on that they are the 3rd best choice and the other 2 prefer to play for NZ and Tonga.
It's not wholesale feasible. Imagine this scenario in several positions.
Especially with Poly players becoming so prevalent in squads....over 50% of rosters now.
Extreme examples for sure...but very likely scenarios in the not too distant future.
SOO should remain as the sole Australian Kangaroos selection competition IMO.
I can see the benefits of having the best players picked no matter what country they play for but that's not SOO. That's another competition all together.
A new comp for Poly players could be set up along Barbarians concept, or similar as their selection comp. There's huge support, and rivalry, from the NZ/Tongan/Samoa/PNG community so could rival SOO anyway.
I'd personally love to have JT play for QLD, but I can see the tribalism that makes SOO what it is, be severely eroded over time, if its not for Kangaroos selection.
Just my opinion
