I'm not saying that at all.
I'm saying if you dump the regions professional club then as time goes by good young sports players will choose league less and less so there'll likely be a switch back to the days when London didn't produce many players at all.
In the good old north in regions where there's no fully pro club the production of professional players is at a low level, but keep ignoring that as you always do.
The argument that it's OK to dump the Broncos needs some meat to it and not the assertion that with no local professional club the area will just go on churning out pro players.
You always make the assumption that kids take up RL with a view to turning it into a professional career. i think nothing can be farther from the truth. I think kids take up RL because they want to try it and then keep playing because they like it. The vast majority will never be either pro or semi pro. This is true anywhere amateur RL is played from Cumbria to London.The ones who do become good enough will , in the case of London, turn semi pro with the Broncos or the Skolars or Hemel and, if they become stars at that level, will move to SL clubs as countless Cumbrian youngsters have done.
A select few will be so good that they will come to the attention of SL clubs early and will move away to join the junior programmes at the SL clubs directly, as, again, youngsters have done from Cumbria.
I think you correlate the impressive amateur and junior development of RL in the South and in London with the existence of the Broncos as a SL team and I, personally, don't think they are connected. i have mentioned this before but where is the amateur game strongest in London, Brixton, South of the river near Greenwich. in the Gillingham area. Near the skolars in Haringay.
Why is is not dominant in Richmond and Twickenham and Brenftord on the doorstep of the Broncos ? According to your theories that is where the strength of the amateur game in London should be fostered by the allure of the SL Broncos in the area.
I don't think this theory holds water. The junior/amateur game is similarly making prgress in Wales and the North east and the Midlands with nary a whiff of a SL club on the horizon.
The added option, hopefully, in the future, will that the Broncos will be psuhing for readmission to SL via promotion and will keep some of these stars on the premise that they can get to the top level by helping the club get promoted.
To summarise, I think junior RL will continue to thrive in London irregardless of the professional level of the Broncos and talented youngsters will still be able to gravitate to the higher levels if the game.
This has been the case in Cumbria for the last twenty years since Workington were the last SL club in the area. Why should the same scenario not be applicable to London.
