Does a kid care about being outside the cap? I don't think that's going to drive your price up.
If you go to Rugby at 17 and even if you play for the Wallabies which I would think is rare- how many 17–20-year-olds In the World Cup Squad? There was one under 22, and he didn't play a game.
21 years old you say I want to come to League, Jorgensen is a great example, Union kid, dad played for the Roosters and only 18. So he's going to be a target.
Is his price going to be that much more than what it would have been if he'd just gone to League at 17? I would still only think he's going to command $250k-$300k. he's not suddenly getting 800k because he's played a dozen S14 games.
I don't think it's for the 17-year-old, it's for the NRL to buy Lomu and stick it up Rugby.
