Amazing bowling talent, but Smith and Warner aside the batting is either unproven or shown to not be up to test standard.
You've got Burns, Khawaja, S Marsh, M Marsh, Voges, Ferguson, Nevill in the top seven at different times batting around the two world class players. Ferguson is an unknown after one test, Darsh is inconsistent and often injured when in form, his brother isn't up to it, Burns doesn't look like he is either, and Voges has surely passed the point of no return. Khawaja is also an unknown quantity against quality bowling, though tbf he batted well here second dig.
