Don't think that the AP is to blame and all to do with poor elite coaching team.
How are Wales, Ireland and Scotland doing better? They got to the QF, Sco and Ire having qualified through vastly easier groups. No great achievement there, and if they think that's a success more fool them.
AP is a more competitive league than PRO12 and Top 14.
6N does however need looking at with at least the introduction of bonus points.
Pro rata strictly from player numbers then certainly Wales and Ireland out perform England, Wales improvement has come since the regions began and is a direct result of the regions although I am still not happy with the way they were set up and would much rather see 2 regions an East and West.
The following are rules applying to Welsh Premier league clubs, another plus point in the development of Welsh players -:
Premier Division Clubs and Championship Clubs who have been granted an A Licence
pursuant to the National League Rules may register up to 2 non-Welsh qualified players who
will at any one time be eligible to play for it in the National League (i.e. if one or both nonWelsh
qualified player(s) leave the Club he/they may be replaced providing the number of nonWelsh
qualified players at that Club does not exceed 2). In the case of a professional or semiprofessional
player from outside the EC and who does not have EC workers rights, a licence to
employ the player must be obtained by the Club from the UK Border Agency. An application
for a licence to employ a professional or semi-professional rugby player has to be supported
by the Union. The WRU will not support an application for a licence to employ a professional or
semi-professional rugby player other than an application made by a Professional Region, a
Development Region, a Premier Division Club and a Championship Club which has been
granted an A Licence pursuant to the National League Rules. The numbers of non-Welsh
qualified players which may be registered and/or contracted by a Professional Region is
governed by the Rugby Services Agreements between the WRU and the Regional
Organisations.
