It took me a while to realise why Wales are capable of winning cheap Grand Slams every four years and the answer is World Cups. England Italy Ireland and especially France introduced new players to start the build towards the World Cup in 2011.Wales played the same team that couldn't get out the group stage. The best Welsh player in the tournament is 36. They were just about the best team but I would be worried about the future as the others will get better.
