I remember watching the World Cup in 2015 thinking how lucky we were to have so many match winners with the bat and ball and how our selectors had managed to capture the spirit of the new style of ODI play, while laughing at England getting knocked out by Bangladesh.
A lot has happened in the three years since.
Having said that, I think the domestic BBL series is playing with the selectors heads (and I reckon Cricket Australia might have a say in which BBL players are 'released' for International duties). I'd hope that with a clean slate that put together a better squad.
At least you'd hope so. Some of Australia's selections for this ODI series are bizarre to say the least.
