1. I disagree, the gap between England and those nations is so considerable that any benefits to those nations are outweighed by the damage in taking away the tradition of GBRL.
2. I completely understand the reasons for it, I just think it was too idealistic and has massive flaws. Even in the best circumstances we're talking about a process that would only see real benefits in 20/30/40 years time and may in reality never see any benefits. On the flip-side I think we'd see a situation where the likes of Iestyn Harris, Keiron Cunningham and Lee Briers would never opt to play for Wales now if it meant never genuinely competing in a top-level international game.
3. At the current time, when the Celtic nations have literally hundreds of players and play in front of hundreds of people, their best players should be able to play for GB as well as their own nation but in different tournaments. Look at the Evans brothers, they are proper Welsh but have opted to play for England to play in the big games.
1. The benefit to those nations is that they exist. The gap between them and England is irrelevant. England (hence GB) are so far behind Australia, and have been for three decades now; should we do away with England/GB? And any damage that has been done by taking away the (relatively recent) tradition of GB is an issue that English rugby league has to face up to. Which other major team sport in England would want to subsume their national identity - and their national team - into a shared representative team?
2. Having national sides for nations that play the game is idealistic? No, it's just the normal way of the world in team sports. Of course it may be 20/30/40 years before we see the benefits of current developments, but here's the thing: to realise the benefits of a process that takes 20/30/40 years, you have to persevere with it now! As for Welsh players opting for other nation's teams, that is an issue for the game's authorities and the individuals concerned. It is up to the game to provide regular access for second-tier nations such as Wales to the big three, whether in world cups or through qualifying for the 4 Nations. Under your suggestion, Wales, Scotland and Ireland would never get to play the big teams, presumably having to be content with a never ending cycle of games between themselves.
3. The Celtic nations may be small at this time but don't think that nothing is going on. I am literally bombarded with messages about the development activities going on in the Scottish game, whether that be school games, development squads at various age levels, student trials and 9s tournaments, wheelchair RL, coaching and official courses. The game in Wales is even more advanced, and I'm sure the Irish are getting stuck in as well. Yet you think it would be a good idea for the three teams never to play in a world cup again? And never have access to a 4 Nations? And what other tournaments? A Celtic Tri Nations?
