Looks good, the only change I would suggest would be instead of having the National South 1 & 2 Divisions, the short to medium term aim should be a National South (West) and a National South (East) directly below National South. Or Even a Midlands/South split, as long as there's some regionalisation, as we're at least 20 years away from being able to sustain 3 divisions that cover the whole of the country south of the M62.
Just out of interest though, where do Scotland and Wales fit into this structure?
That would seem to make more sense, as I can't see it being that easy for even the strongest clubs in the midlands and south to cope with the organisation and travelling needed, never mind those clubs 1 and 2 steps down.
The more I look at the proposed structure the more I struggle to relate it to the game outside of the 'heartlands'. In some ways it looks the kind of structure any one of us on here could have dreamt up in a spare 5 minutes at work - especially one of us who isn't that familiar with the trials of running a club away from the north.
I know the RFL have been consulting the northern winter clubs about making the switch to summer, and I know the clubs and players have been giving feedback, but have they also been doing the same in the south and midlands? And have the clubs and players been requesting the proposed set-up?
To me part of the presentation of this structure is about the politics of the game. I think, quite understandably, that the RFL wants to unify the game by getting the greater part (or the most important part) of the winter game to join the summer game in playing in the summer. To that end, playing in an integrated 'national pyramid' must appear attractive to a lot of clubs and players and will be a selling point in favour of the switch; and it is definitely feasible - in the north.
Something like the diagram needs to be the long term aim for the game outside of the north, but not necessarily for implementing at this time. It has to be done when the game in those regions is ready for it, not as part of a revolution in the more established parts of the game. Still, everything will come out in the wash, as they say, but I just hope development area clubs are not being pressured into accepting an unsuitable structure that certainly looks good on paper.
