At full strength, this Australian team needs a few key ingredients to make work.
Successful opening partnerships in ODI cricket generally require an aggressor and an ultra aggressor. Over the years we've seen the following:
Jayasuriya and Dilshan
Gilchrist and Hayden
Sehwag and Gambhir
Gayle and Misc
McCullum and Ryder
etc
With all the players on the left being the 'ultra aggressors' usually scoring at a lightning strike rate and changing the balance of the game. Then on the right you have the 'aggressors' who still score very fast compared to a lot of the players on the team, but less so because they play the anchor role and try to bat through the innings. At the moment we have Marsh opening, and he just seems to have no fluidity in his innings with a strike rate of about 75. That kind of thing was suited to maybe 10-15 years ago with a real rock at the top of the innings but not so anymore, the game has changed. That's why Warner would be such a cornerstone if he could come good, he could provide us with a Gilly-esque start and change the game for us. To partner him would be Watson because he brings balance to the team and can play the aggressive anchor. Hence opening combination is:
Warner
Watson
Ponting
Now I'm also in favour of the Haddin opening theory because yes he is wasted that low and can strike a ball very cleanly and he adds impotice to the innings. But I guess we can only pick him there when/if Warner fails.
Now as I said before with the middle order you need that formula we had back in 2006 when Martyn was still playing, so it's just a straight swap for Hussey
D. Hussey
Symonds
Clarke
M. Hussey
Haddin
Which is perfect because at the moment, Clarke is coming in too high and probably can't stand the pressure hence only averaging mid thirties since the 2007. That's obviously made worse by the fact that our opening combo is currently green and likes to lose wickets early so if he bats 4, has to come in even earlier which is not good.
Finally with the bowlers, we have to have systematic selection system where we pick from a pool of bowlers rather than just by random from the domestic scene. IMO this should be the pool when everybody is fit;
Lee, Bracken, Johnson, Clark, Hilfenhaus, Tait, McGain. Now obviously the first three positions are already nailed down with
Lee
Johnson
Bracken
Hilfenhaus/Tait/McGain
so the hard part is just deciding if the last specialist bowler is a spinner or quick which is relatively easy.
To summarise we get:
Warner
Watson
Ponting
D. Hussey
Symonds
Clarke
M. Hussey
Haddin
Lee
Johnson
Bracken
Hilfenhaus/Tait/McGain
An almost perfect squad with 4 specialist bowling options so we shouldnt' get situations where we struggle to bowl out sides, and also a Watson to come in and keep it tight with maybe Hussey and Clarke to also chip in with with a couple if need be. That batting lineup is probably the most solid in world cricket (bar SA who've got Bradman in their team).
