The issue is that England know we'll just take our best 3 quicks in Australian conditions so they prepare pitches that suit Anderson and Broad (and our attack is blunted). Rather then adapting and mixing it up with at least a couple of bowlers that will be suitable, we're too scared to drop one of them and like last time, wait until a dead rubber before trying someone different like Siddle.
We can prepare all we look with Aus A vs Aus games over there but if we aren't prepared to make the hard calls to get the most suitable team on the park it's not going to matter.
