Believe me, there is.
Salford & Manchester have a combined population of approaching 3/4 Million people. There is lots of talent here. It's just a matter of looking in the correct places.
Wythenshawe, in the south of the city, has a population of approx 85k, which is bigger than most traditional 'rugby league towns'.
I don’t understand your post in any practical way whatsoever?
You may mean that if everyone played Rugby League and all other sports and pastimes were banned we’d beat the Australians all the time and have 200 professional clubs.
But I don’t know of anyone from Wythenshaw playing RL and going on to turn professional.
I do know from a lifetime of experience that in a free country that RL is the choice of a minority of people. The games too tough to ever spread with any popularity, even the historically geographically spread union sees massive drops in numbers playing at the clubs, with “fourhs” and “thirds” closing.
Only where the game is successful historically and successful in Superleague can any club turn out a professional quality local born first XV11. That’s in places like Hull, Wigan, St.Helens, and Leeds. Even the Bulls massive success post 1995 hasn’t seen participation levels rocket that much, and where a club is in decline like Widnes post 1994 the local junior scene can decline just as alarmingly.
That is the situation in practice, that any club even with an army of volunteers can change en masse the mindset of the mass of kids who don’t want to favour high contact sport over soccer in particular is positive thinking yes, but…
As for Salford even in their early seventies hey day the players were all but Sammy Turnbull shipped in from here there and everywhere. Building a winning side like that necessitated a club not just to spend money, but the biggest money. Today no SL club can outspend another. No SL club that cannot match the salary cap can obtain quality talent, no club at all that cannot pay £1.6M in wages a year can hold onto the talent that is in short supply and always will be.
