In Australia they are all concerns. That doesn’t mean they will all go great this series but all six of them are real threats in these conditions. Burns averages 55 against NZ from five tests (2 x 100, 2 x 50).not to disrespect the other three but really Smith, Warner and Labuschagne are the only concerns. The other 3 haven’t done a lot wrong but they’ve also not proven themselves impervious to decent bowling.
