Whilst you can use the Leeds city example for the decline scenario when one team dominates, it must be qualified. Bramley had a decent little ground with a "only for sports" clause in the deed of gift and that was circumvented and the ground disposed of.
These circumstances did not exist in the Calder area.
Indeed Bramley had their own ground and developed it in 1966 into a more modern stadia. It was to be their saviour and take them up the league.
But in 1973 the clubs voted to break into two divisions. As a Bramley director said to me "That eventually killed us, it removed our plum fixtures like Leeds, Wakefield and Bradford. These fixtures paid the bills".
Bramley however started IN that first division coming 12th. and they won the floodlit trophy too. Soon after they slipped to relegation and the only way was down, despite getting back in at one point.
Under new Directors I still got the same candid comments that the club could not survive in the second division. A simple thing like a ball converted over the posts, over the social club and down the Aston's and lost was £30 Ronnie Teeman could not afford. By 1995 they were near the bottom of the league on crowds of 800.......
The self same crowds Featherstone were dropping to in 2006......
The sort of crowds Hull.K.R. were heading for at one point.
The board gave it up. It was not going to work playing losing Championship Rugby and the club tried to survive playing at Headingley as Leeds "A" team where Barrie Mac, most famously made a comeback from injury.
Nobody came in to rescue the club. There was no Mark Campbell, there was no Neil Hudgell either for Bramley and in those circumstances the only way was down.....and out.
To argue that these circumstances could not exist in the Calder area like you argue, or to state like Terry he could not see the same thing happening is to fly in the face of the facts and realities.
How would Featherstone have done without Campbell and without their plum fixtures of Wakefield and Cas? this last six years.
How would Hull.K.R. have done without Hudgell this last six years??
Don't put your fingers in your ears and your head in the sand and sing la la la la la. Deal with the debate. You want to be in it so come on, deal with it.
The demise of any RL club is monetary, and when things get too much, which is usually when nobody wants to prop the club up anymore with their fat wallets all that remains is the asset of the ground.
You seem to want to dream up special and different scenarios in Leeds because you will not face facts and reality.
Hunslet were down to absolutely skint, near the bottom of the league and few fans BEFORE they sold of their only assett - Land.
Bramley were down to absolutely skint, near the bottom of the league and few fans BEFORE they sold of their only assett - Land.
Swinton were down to absolutely skint, near the bottom of the league and few fans BEFORE they sold of their only assett - Land.
York were down to absolutely skint, near the bottom of the league and few fans BEFORE they sold of their only assett - Land.
Rochdale were down to absolutely skint, near bottom of the league and few fans BEFORE they sold of their only assett - Land.
Oldham were down to absolutely skint, near bottom of the league and few fans BEFORE they sold of their only assett - Land.
And what of keighley??
In 1987 they had only 445 fans and were SKINT don't you remember they had to sell the training pitch off?? Do you not recall them selling off the Cricket field to keighley CC?? Don't you recall them selling off the whole darn ground to the CO-OP?
Luckily

they were rescued again for their Cougarmania stint in which they again blew up a massive financial bubble and "pop" it went again. I find it astounding that you cannot recognise that but there for the grace of god (or another local businessman to try to turn back the tide) could go many of our great clubs including ones currently at the top of the Championship or Superleague.
This is always your argument that Oldham once won three major trophies in 1957, Hunslet once won all four cups, and so these fine clubs can do so again.
NO THEY CANNOT unless they have enough fans, enough quality players and money of their own, which they don't AND get in on sharing the SKY money. 1973 was the date the big clubs first stuffed the small clubs for their own survival and advancement. 1995 was the date the big clubs again put the boot in along with SKY to stuff them further arranging heavy cash subsidies for an elite and nothing for the rest.
Now back to the OP. Tieing up CC clubs to SL clubs as junior partners may well be the third and final nail in the coffin of several more clubs
Let me get it on record for you. I was NOT THERE at the 1973 vote. I was NOT THERE at the SKY meetings, I have had NOTHING to do with all these events. Let me put it in a nutshell for you - having a go at me because you don't like the facts isn't going to change them

now try and deal with them.
