I wouldn't say a dearth, but not the depth available in recent days gone by.
The younger players still not consistent, the contenders (Khawaja / Ferguson / Marsh etc) didn't have good seasons. Also, there were a lot of good bowling wickets in Oz this year. I think this is one reason why the established players (Voges / Rogers / Katich etc) did well by comparison.
10 years ago there would be 3 batsmen in each state that were capable of test cricket, this isn't currently the case.
I do like that the team is heading in the right direction, a review, followed by action and a plan to rebuild wont change things overnight but there has been significant improvement in most departments.
you should also understand the Sheffield Shield is and always has been of a significantly higher standard and tougher breeding ground than county cricket.
