If I understand your last phrase..........
Another way of looking at this is : Are the top clubs in SL looking to create a barrier to SL entry by stacking Swinton, Dewsbury and Hunslet with SL squad players so that they block the likes of Fev and Halifax from winning the Championship and the NR Cup, thereby not being able to apply for SL?
I think we all love a conspiracy theory Shaun.
I think SL clubs would love to cement their positions in SL forever, and would welcome obtaining the resources of their local CC clubs for themselves. Wigan would probably like a couple of thousand more fans and the LSV as their second team home, with the kids from Leigh miners and rangers all busting a gut to play for Wigan one day.
Leeds are well on the way to securing SLS as their second team ground, the locals mainly watch Leeds and the best kids bust a gut to play for Leeds, McShane was educated a drop kick from both Parkside and SLS.
An intentional ploy to keep Leigh, Fev and Fax out?
I should not think so Leigh and Fax suffer from the size of their local rivals. Featherstone are a different kettle of fish, but if they could become the big club the (Lower)Calder area needs then I'm sure SL would want them to get on with it ASAP.
