Smith was withdrawn through injury.
Warner was rested and Khawaja was sent to Dubai early to train in the conditions (and presumably work on his batting against spin).
This is the bit I struggled to understand. It's not as if Handscomb has experience in the sub-continent either yet they sent him to NZ and have now undoubtedly rocked his confidence.
It can't have been helpful for SMarsh or Maxwell to be facing the white ball with India on the horizon and it doesn't seem as if NZ was beneficial for them either.
In hindsight perhaps we should have thrown out the 'future planning' agenda for this series and picked a balanced experienced XI like:
D Hughes (386runs @ 64 in Matador Cup & 304 @ 43 in BBL)
A Finch
M Klinger (236 @ 47 in MC & 334 @ 37 in BBL)
T Head
M Henriques (414 @ 69 in MC & 263 @ 29 in BBL)
C White (457 @ 76 in MC & 227 @ 32 in BBL)
B Dunk
J Faulkner
P Cummins
M Starc
J Hazlewood
Stoinis could have slotted in anywhere in the middle/lower order.
