Like England in some ways, there are unanswered questions. If you ask who Australia can write in in ink, definite world class options, you have:
WARNER
X
X
SMITH
X
X
X
X
STARC
X
X
So not many. If you start adding in the guys who deserve a decent run in the side, or who are clearly the least worst option, I reckon you're up to:
WARNER
X
Khawaja
SMITH
X
X
X
X
STARC
Hazlewood
Lyon
So short an opener, and four slots in the middle. I might be being just a little harsh on Nevill, who is solid, and there is at least quality cover in Wade, Payne and surely Whiteman at some point. Mitchell Marsh balances the side, so is worth keeping. So three....
...still not ideal...
