NZ's golden generation i think is still ahead... Madge should be amazing for them.. The pressure is off at the moment because noone expects them to do well.. Aus has just lost a bunch of players i don't think they will replace and so are coming back to the pack and the emergence of the island nations is going to make International RL viable even when Aus isn't playing. The trick is that NZ needs to keep churning out the talent. They have 3 and a half years to get themselves on track.. i think they will.
I hope our golden generation is still ahead - but another bad coach and we're stuffed again. We had the best forward in the game and our coach chased him off.
Origin also screws us, despite being Aussie born, if Origin didn't tie him to OZ (e.g. he could play for Queensland and NZ) we'd have Ponga going forward, instead he's going to be a Kangaroo. I wonder if a 20 year old Foran would have committed to NZ if he was coming through - probably not, he would have looked at the Kiwis shit show last year and gone with NSW (I wonder if his decline would have happened at the same pace ...)
And that's a depth thing, Aussie could afford to lose a guy like Ponga, they've got lots of talented youngsters coming through but NZ can't - to be competitive we need all our guys.
I wish I could be as optimistic as you, but sadly it appears, when it comes to international league I'm a whiny pessimist.
