The main variable that we could alter is the way that Welsh youngsters are brought on. It is a topic that has been repeatedly talked about on this site.
Historically we have had successful age group sides and individual players doing well but then something seems to not happen between the ages of 16 and 20. This has been the case back to the likes of O'Shea and Wright and seems to be continuing. Hopefully the revised development pathway will work but it is the same people and it will take time.
