The idea of expansion of our great game has been a dream for the 60 years I have been watching our great game. Sadly it hasn't happened. Justifying this argument where are Scarborough, Mansfield, Kent, Chorley, Carlisle, etc. they are all no longer playing semi-professional rugby never mind professional rugby.
Newcastle is an exception. They have a wealthy chairman who funds both the RU and RL sides. SL now has all the money strings and they are only concerned about self and the rest will either struggle on a little bit longer or go bust.
Looking at the amateur game, many cubs had two and some had three teams, now some struggle to field one side! The major cause I feel is summer rugby. Players in summer have too many other things to do but during winter there are fewer distractions. Another causal factor in the reduction of players is the demise of RL in the schools for whatever reason.
To sort it out is a massive task of the RL but sadly they will continue to bury their heads in the sand until all that exists is SL That is until Sky pulls the plug!
