I am NOT a fan of all this Aaron Finch test talk.
Being able to slog on flat pitches and clear small boundaries =/= good test player.
If he can consistently do well in the shield over the next 2 seasons then I would be delighted to see him have a shot. But at the moment he should be well behind Hughes, Bailey, Khawaja, White, Klinger, Wade, Burns, Maddinson, D Hussey, Fergusson and others. That being said, our selectors seem to have an enormous boner for him at the moment so anything is possible.
Edit: Plus Voges, Cooper, Marsh, Doolan etc. Basically anybody who can bat and doesn't have the initials GM (Greg Mail excluded).
