Test rugby seems to be undergoing some sort of renaissance. Following on from the WC, crowds are undoubtedly higher than most wold have expected. Perhaps hopes of a legacy weren't misplaced.

It needs to be built on; as Rogues says, international development is to some extent governed by numbers prepared to pay to watch what's on offer. The idea of a series for tomorrow's players is sound. To me, it offers a deal more than the recent game the seniors played against France.

I wouldn't say it's undergoing a renaissance. I just think the people running the game are starting to realise that creating big events is what gets people interested in attending these kind of games. having test matches at places like Leigh just sends out the wrong image to the wider public.
Also, having test match RL back on free to air has helped too IMO.

A think the attendances also show how well and strong the New Zealand team have done over the last few years.

GB/Eng vs Aus was always the big one over here, and whilst facing New Zealand was also big it fell behind playing Aus in the pecking order. But this fixture particularly off the back of the games in 2013 & 2014 between the two has increased the appetite to see them face off again.

It will be interesting to see what grounds/capacity get Eng vs Aus and Eng vs New Zealand in the next Four Nations in England.

That's a renaissance in my book
