Now THAT is a great question. One that the RFL will be struggling with I'm sure. But the RFL thinks, and I agree, that Wales is so far a worthy cause.
I do draw the analogy between RL expansion in England and Aussie Rules expansion in Australia. Sydney entered the Aussie Rules comp in 1981(I think) only recently did they stop receiving special treatment as an expansion club. 25 years seems a long time but it was necessary. There's now a second team in Sydney. In Australia RL expands in its heartland - successfully these days - but Aussie Rules has been recognised as the country's no.1 football code and people in Melbourne / Adelaide / Perth know little or nothing about RL. The Aussie Rules TV Income dwarfs Rugby Leagues. That could change with the RL Commission over time but... we will see.
Personally - I think 25 years is too long for Wales, but 10 years is necessary to support.
London... well it should be standing on its own two feet by now... We should be exploring why it isn't and fixing that. They should be reducing the reliance now on overseas players and have an expectation of crowds in excess of 5000.
Again, that's my opinion.
That is your opinion and your opinion does have merit but that is absolutely not what the RFL is doing in practice.
Gateshead a geniune expansion was given one year in Super League with average crowds of over 4000 had the rug pulled from under them to save Hull FC and to give more funds to other SL teams.
Sheffield a genuine expansion had the rug pulled from under them 2 years after winning the Challange Cup at Wembley to save Huddersfield Giants and to give more funds to other SL teams
Paris was tried but the RFL pulled out after 2 years becuase it was losing money
South Wales were given 1 year in SL , Leighton Samuel stated at the time he wanted to continue but that all the RFL were interested in talking about was getting their money back.
The AFL expand to Sydney 12 hours by coach from the heatlands population 4 Million
The NRL expand to Melbourne 12 hours by coach from the heartlands popultion 3 Million
The RFL expand to Wrexham 25 minutes from the heartlands population 40,000
The NRL knew that Melbourne would lose money and stated they were willing to help fund them for as long as it takes
The RFL wanted their money back after 12 months and pulled the plug on South Wales moving them 150 Miles North to virtually the end of the M62 Corridor.
The RFL pulled the plug on Gateshead after 12 Months.
Once you start a team and pull out , the ARL / NRL mucked up in Adelaide and Perth you upset your potential support and it makes it more difficult.
It is better not to bother than to do this.
The Charge against the RFL is not that they are Anti - Widnes ( I don't believe this is true) it is that they are incompetent, not-transparent and dishonest.
