Pretty much.
We have a shocking top order, further limiting our batting is not the answer. Pick 6 bats, a keeper, and 4 bowlers. It's worked for 100 years.
Yep, and if the keeper averages more than 35 its a bonus - so long as they are the best keeper (which I think Paine is anyway)
I'd be going:
Warner
Harris
Khawaja
Smith
Patterson
Burns
Paine
Cummins
Pattinson
Lyon
Hazelwood
Starc/Richardson/Labuchagne/Renshaw/Handscombe/Wade/Sanga (the traditional young bolter).
Would be nice to have a true leggie, but wouldnt just pick one for the sake of it. Either Wade or Handscombe can be reserve keeper, but these days you can just fly one in if you need to
