Of course they should, this was a job for the proposed merged Manchester club, and post refusal to merge became the task of Salford, if Salford wither what resources will be left to do this, to what purpose????
Why has the area regressed????
Wythenshaw was a red herring.
It might have been a red herring but it wasn';t thrown by me.
I can tell you how RL in Manchester has regressed. In my lifetime there have been four senior RL teams in Manchester, Broughton/ Belle Vue, Oldham, Salford and Swinton. When I started watching RL in the early 60s, Belle Vue were already gone, having failed to find a suitable ground and having moved far away from their roots in Broughton.
Oldham were a big deal, always in the top part of the league, champions at one point, numerous internationals in their ranks, decent crowds and their own ground at Watersheddings. They could never quite keep up with Wigan and and Saints and they slowly declined even with several periods of success interspersed with the poorer years. They were in several CC semi finals but could never quite make the breakthrough and have never played at Wembley, more's the pity as I think a Cup win would have done wonders for their support. They made the inaugral SL but went bust after the first season ( I think) Although Watersheddings was theirs it needed major work and they sold it to pay their debts but went under anyway. Chris Hamilton resurrected them they went on a trek through Southern Lancashire searching for a ground, losing CC finals with monotonous regularity and gradually losing many of their specatators who had rallied to the cause on their initial reformation. They have gone through several financial crises usually owing the IRS back taxes and being shafted by Oldham Athletic but have survived and are finally showing some small signs of life, having finally moved into their own ground back in Oldham and are hoping to upgrade it and win promotion this coming season. Why did they decline, you ask?. I think they were no different from many of the clubs in the 60s, 70 s, 80s and 90 s in that they were part of the general decline and malaise that affected the whole game. Other teams were in dire straights too but managed to find investors or had better management whereas Oldham didn't and I think their failure to win any major Cup or Championship didn't help their cause either. That is just my take on it and I might be completely wrong.
Swinton were also one of the big clubs. They had a massive, test match sized ground at Station Road and were Div 1 champions twice on the trot in the 1960's averaging around 6,000 per home game. they too had a team full of internationals at that time. Station road was also decaying and needed major improvements and was too big for their crowds in any case. They tried to stay with the elite clubs but, again, as with Oldham, despite several better seasons, gradually declined and eventually sold off the ground to pay debts and moved out of their home town to Bury and have never found a home ground since being currently at Leigh. Once they left Swinton, any residual support melted away. I can't comment on their management but I think it made several big mistakes and there was no investor to bail them out. Hopefully the new proposed ground at Agecroft will come to fruition and they will, at least stay in CC and build their crowds to a decent level.
Salford were the weakest of the lot. They had never been anything since the late 1930's but stayed in the league. I remember going there to watch Keighley in our promotion season of 1962 and Salford were in the bottom four of the second division. They never lost the ground however and Brian Snape and later John Wilkinson put money into the club and they became a big deal glamour club with an all star team, a night club on site and were quite the pin up boys of the league and their crowds refelected that. Somehow they also declined from that pinnacle and had good and bad years but Wilkinson never left them and financed them a lot. They have finally lost their stadium at the Willows on the hope of a resurrection at the City of Salford ground but I think the rent there is a major factor in their present financial crisis with the gates never rising to the 8,000 they needed to make ends meet.
You Ask why though and I am at a loss. The one constant amongst all four teams is that on loss of their grounds they almost went belly up. Not staying near their roots was another factor in the decline of their support also with the exception of Salford. Maybe the inexorable rise of Manchester United from big to mega also impacted on the Manchester RL clubs. I don't know, that just a guess.
Salford are salvageable. They are in SL. They have a new stadium. Maybe the rent can be reduced. Let s hope they find a new investor?
Swinton are worth saving. They have a long and glorious history and I think they could be a decent community focussed CC club if they can get their ground situation sorted.
Oldham is much bigger than Swinton. They are somwhat isolated on the eastern side of Manchester. They have potential in my opinion but have a very long row to hoe before they can realise it.
You ask to what purpose should we try to salvage RL in Manchester. There is still a legacy for the game in the city. we should not let it die. Manchester is a media mecca. the game needs a presence there. I have read post from you before championing the big city concept for the game. Well, they don't come much bigger than Manchester. It's worth fighting for. The game cannot afford the geographical footprint of the still important heartlands to shrink any more. A strong club or two clubs in Manchester with a growing junior development is just as important as London. Does the game have the resources to do this? I don't know but it should take a serious look at the situation. Contraction is never good.
