That's not the problem: the issue is that there's no money in union between 18 and 20. I gather Tyzac gor his dream job and so no doubt that removed that issue from equation.
Who are you going to offer the very limited money to? The requirements of the 2 codes are really quite different. Tyrone is with bunnies and he may flourish in league but give his well known aversion to the forwards it's hard to see him getting as far in union as league - but if you want to stop him going you'd have to pay him.
And so it goes: we keep tyzac because he's got a job in a career path we lose Tyrone because the bUnnies presumably pay him.
What job? You've got your wires crossed there.
Mohi and Jordan chose rugby because they enjoy it and believe they have a future in the game. The promise of rep honours etc .. Mohi has already played U20s NSW.
The ambition of playing for NSW U20s and Australian U20s is motivation enough for some players. And maybe being picked up by a Super rugby team.
Short term goals aren't what motivates some players.
Some players get educational opportunities and take it while playing a game they enjoy with their mates. And hope future rep honours eventuate.
And of course there's always the line of thought that if a player establishes himself in rugby or shows promise, he will be offered good cash further down the track to play RL. That can be a long term consideration.
