Imagine you have 10 years of high earning capacity. That "trust account" at the end of a 20 game career is holding well over 200k, plus the 200k previously earned and payed. 400K is some serious bonus for a ten year career, what a year's extra pay? 10%. Fools not to take it.
Also, generally the foreigners and kiwis are first signed to play origin when they're on much smaller "pre-star" contracts, or on their initial first grade deals, which makes the pay increase SUBSTANTIAL comparatively. You seriously don't think Tamou cannot enjoy the extra 30k now? To put toward a house deposit, flash car or sweet off season holidays? You're silly to think otherwise.
It is a very short career these players have, and for the vast majority, they will NEVER EVER earn that kind of money per annum again. All the players are very well aware, that tomorrow, they could receive a career ending injury.
And now they talk of next year it being 50k per game, instead of 20k...
Making a 20 game origin career worth another million?!
