Personally feel Australia are massively overrated.
Okay !!! It's your view. But ideally I won't write this side off as they have won 5 WCs and definitely I've made this mistake in the past.
Their batting lineup looks extremely imbalanced.
Still very well capable of scoring 330+
Starc hasn't played a single ODI this year, and wasn't good last year either.
Didn't play much last year either
And as for how Australia should play like Australia (no idea what that means either),
This
The strength of the Aussie side has always been their mental fortitude and ability to handle pressure
India's problem isn't the lack of ability or skill to score 350+, it's their tactical approach to the game that's holding them back
This happens due to the fear that if they try force things they might lose their wickets and if they actually do then think of the consequences and as far as I remember in the last WC the teams who saved their wickets till the end and scored 240-250 in 40 overs more often scored 350+ then teams who went after everything. In ODIs you have the opportunity of wearing out the bowlers of opposition and that's where India has always been good. They failed to do anything only because of instability in their line-up. And this time they are going into the WC with a much more settled line-up. So, I definitely don't see a need to worry over here
A bit off-topic
I like they way you put up things. You post very respectfully and the format in which you put up your points, I mean the pointers format it is just wonderful. Your knowledge regarding the game is just wonderful !!!! You are different from the few members over here who just throw insults at other members on this forum just because they believe their point is being misunderstood or they misunderstand others point and they are too rigid enough to change their attitude towards others
