It shouldnt be a problem, i've heard loads of quality players are being produced in Wales and London, in a couple of years SL is going to be chock-a-block with players from expansion areas

you're right of course it will devalue the SL if money isn't pumped into SL to give it a chance to keep up.
But we,the humble fan,can do very little to change this trend.If the overall quality drops,then so be it.It doesn't mean we have to stop liking and following our sport,just accept the lower standards,realise we will be even further behind the big two internationally and just get on with it.
You can't change the inevitable....

surely the question should be. why do we import overseas players in the first place?

it is a quick fix, laziness on the part of the SL teams. spend more time and money on good scouting and good coaching and develop our own players.

there are loads of very good players in the lower leagues that with full time training and good support would be easily good enough to play at SL level yet are not given the opportunity.

The rules regarding home grown players takes time but the first shoots are definitely showing-Cas last night had a number of good kids playing, Quins have 10 + in there 25, Wigan as ever have a great through put, Leeds with BJB, Watkins continue with great youth, Saints etc. The future is like what we all want. I suspect clubs will steer clear of the NRL going forward- Big money doesnt always produce big performances from them
