Ireland have done a bit of that but nowhere near enough. They have about a three month break at the moment I think and this is because the lower ranked teams such as Bangladesh, Zimbabwe, West Indies are scared of playing them.
I think it's more to do with scheduling conflicts rather than fear. The calendar is so packed now there is little time to fit in much more cricket.
I was hoping Ireland would put a better showing against Australia A. Paul Sterling's innings lived up to his name, but the depleted batting lineup showed its fragility. You don't always see two declarations on the same day's play (three if you include Aus A's overnight first-innings declaration), but losing 92 overs to rain over the first two days will change the game. It would have been nice to see Ireland bat some more against (effectively) a Test bowling lineup.
I fear that the uninformed will take a passing glance at this scorecard and unfairly conclude that the Irish aren't ready for Test cricket. Regardless, if Ireland and the other leading Associates don't get to play Test teams outside of global events, games against national 'A' teams are the best consolation. This needs to become commonplace, especially for Ireland.
They need to play much more cricket against "A" sides, one off games such as this one are no good if they happen once a year, there's no real scope for development in the odd game. With a lot of the Irish guys playing county cricket, I would have thought Ireland would spend time in their summer playing practice games against "A" sides or even some state teams (Western Australia, New South Wales, Canterbury etc).
The ICC need to smarten up in this area and actually give Ireland an opportunity to develop themselves to the point where they are bashing down the door of playing test cricket.
