Seriously who really cares about the 7's? It is strictly a development tool and early talent identification.
Sure it is great to win tournaments and commonwealth gold and other stuff but really all the 7's are really there for is to give Super 14 franchises a look at some talent that is coming through the ranks.
Every time that a new talent emerges a Super 14 franchise will come in and offer them a professional contract - this is great overall for NZ talent and the NZRFU obviously encourages it.
All it means is that the New Zealand team will always lose talent as it is identified. And this isn't a bad thing even if they lose their stranglehold on the series.
