I think it provides some insight into the health of the game in various states and explains the whole 'NSW bias' bull.
Victoria and South Australia in particular are not performing
Victoria aren't performing because their system underneath is flawed. South Australia has a similar problems. An interesting project would be looking at the Australian Under 19's that fail to go on. Plenty of Victorians in that group who fail to make it. My hypothesis is that the Victorian talent identification system is flawed and skewed towards players who are bigger, because all junior tournaments are short form cricket. We miss the players that we should be putting time into. The end result being we are developing the wrong players and ultimately it is no surprise that players don't make it. By cutting out or sidelining the Grade system, the gap between those that can and cannot gets bigger. It is taking longer for batsman to make it than ever before.
