Here we also have to talk about New Zealand which is badly going down and having not enough time for settling problems with in team because this can give them more poor results in coming matches and specially in T20 World Cup.
Ireland is handicapped by the fact that some of the most promising players have moved to England, to play county cricket. And this is not just the issue faced by Ireland, but also by Netherlands and Scotland. Their best players move to England, leaving these teams to field a second string side while playing against tough opponents. In the end, their performance goes down and this argument is further used to deny chances to them. Imagine how good Ireland would have performed, had Eoin Morgan, Ed Joyce and Boyd Rankin played for them during their peak years.
