Seriously look at what you are writing. I'm sure every young basketballer dreams of playing for the Dream Team at the Olympics. Does that mean that every NBA player should be eligible - cause you know, we shouldn't have rules that stop people achieving their dreams should we?
Do they? How can you be so sure? I think they may dream of beating the dream team at the olympics if they are not US born themselves. But it is a disanalogy - because the dream team is the national team. Teo's dream is probably the same as Karmichael's - which was Origin which then dictated he had to be eligible for Australia. Same with Thorn. It was the allure of Origin which cost the Kiwis these players.
Greenbits - how do you explain Yao Ming playing in all star game but for China in the Olympics? Origin is more similar to the All Star Game than it is to the Olympics givien it is a domestic fixture representive of two segemnts within a nation. If you want to use all star game Basketball eligibility rules in origin- every kiwi would be into that! They could all do a Yao Ming. It would truly help the kiwis no end in retaining players. However, origin was developed to prevent having to represent the area you play in eg Beetson playing for NSW because he played for the Roosters. Clearly he would have chosen to represent Qld should he have been permitted.
However, your argument would mean the English cricket team could not select Keven Pieterson - in fact 4 of their top 6 in the last game were born in South Africa, some having played for Junior South Africa. So these people migrate - but cannot play for their new homeland. Very odd decision. Does not do anything for the person's liberty or acceptance into new country.
Here is the thing you may not realise about Teo (which makes him similar to Kevin Peiterson and not like Yao Ming) - he has moved to Australia and has left a country behind. Now because NZ is just across the ditch i am not advocating that kiwis in the NRL can no longer call themselves kiwis - but I am saying - not all of the ex kiwis still feel like NZ'ers. Some - perhaps even Teo; want to assimilate to their new country.
It is unfair to compare the Rugby League to other sporting codes. In stuff all international sports is the representative pinnacle a domestic series. Basketball has the olympics- most other sports have a world cup - but with League - it is origin.
Player choice is at least a hybrid that would work. But hey - if you want to allow kiwis into origin - by using a basketball system - kiwis will love that. Fool.
