For decade upon decade, Australian selectors have leant to the conventional. Three quicks and a spinner, your best bat is captain, wicketkeeper at seven in Test cricket or pushed up to throw the bat as an opener in the shorter forms.
Occasionally circumstances or an unusual player might shift this around, but it tends to quickly revert to the mean. Having George Bailey in charge has led to an occasional willingness to be different.
His days as a player and captain showed that, and those days are recent enough that he personally knows the strengths of most current players.
It was Bailey’s plan to have Scott Boland play in last year’s MCG Ashes Test, a masterstroke as Boland hoovered up wickets at an 1880s bowling average over the next three matches.
