Certainly Australian cricket is better.
Look at the players that aren’t even playing: Phil Jaques, Test average 47; Brad Hodge, Test average 56; David Hussey, first-class average 55. That short list can quite easily be extended.
The English system produces the odd exceptional player and that’s being generous – more likely it’s just chance and nothing to do with the system. We don’t produce large numbers of high quality cricketers which would create competition for places (as well as better competition in county cricket). Most counties don’t feature a single player you’d want to pick for England.
Is the Australian team better? Let’s see next week. However, if we took a wider sample and pitted the respective second XIs against each other, it’s pretty obvious which nation’s cricket is stronger. Until that’s addressed, England will continue to rely on the stars aligning for their occasional victories.
