4 -3 - 2?

How many sides of top flight Rugby Union can Wales support? 4? 3? 2? 1? See this organ passim for more on this.

I don't know, but I have a sneaking suspicion that with the right people in charge, funneling the revenue into Rugby, and not huge salaries, vanity projects & "support staff", we could manage 4, like Ireland. I still can't see how we should lose Ospreys, Scarlets or Cardiff. For me Dragons are the only club in question. 

Looking north, there is a valid debate about how can a national side really thrive with so many players playing abroad. Good article here. With 4 strong sides, perhaps playing in the English (&Welsh?) Prem, we could keep good Welsh players playing in Wales.
