Former England and British and Irish Lions coach Clive Woodward named George North among those who have come through the Welsh system.
The Welsh Rugby Union elite pathway structure has been singled out for praise by the former coach who masterminded England's Rugby World Cup victory.
Sir Clive Woodward says the focus on developing quality players has helped the senior national side select from strength.
He also pinpointed the establishment of a WRU National Centre of Excellence at the Vale Resort near Cardiff as a key factor.
Writing in the Sunday Times, Woodward said: "Wales realised the importance of quality, not quantity. They have, in partnership with the Vale of Glamorgan resort, established an outstanding centre of excellence.

Woodward also supported his argument by naming key Wales players he says outline his argument.
He named George North, Alex Cuthbert and Sam Warburton who are all players developed through the age grade and 7's structures in Wales.
