Coaching can have a huge impact on any team/individual performance and there's always the ability to improve. I'm not saying they'll win a WC, but the only way to develop is through a postive environment with the best coaches and development programmes. That's before we even get to tactics and any sort of sports psychology. That group of players all have potential, particularly some of the younger players.At the end of the day this crop of Wales players isn't that good. I don't think a coaching change will have much of an impact.
Maybe if they just pretended they were playing England all the time they could have a few more positive results...
