I think with a blunt attack and two of your best three batsman not contributing at all, any side is going to struggle.
BINGO!
Hayden is out of form and has been since the world cup really.
Katich is on fire
Ponting is playing extremely well, though perhaps not quite to the same standard as 3 years ago.
Hussey is out of form
Clarke keeps getting out to stupid shots, but is doing ok
Symonds is a bit hit and miss at the moment, though with his injury we'll be blooding someone new here
Haddin is very hit and miss
Lee is injured and will be replaced by a debutant
Johnson is bowling and batting very well
Hauritz has impressed, though is certaintly still learning his craft and needs pressure up the other end to be effective
Other than one spell Siddle has proven to be ineffective at the top level thus far
So there we have it, out of the last 11 to play test match cricket for Australia you have:
2 form batsmen
2 batsmen who are doing ok (though one is injured and won't play in the next test)
2 out of form batsmen
1 hit and miss keeper-batsman
1 form bowler
1 out of form bowler who is now injured
1 inexperienced fast bowler, who has been ineffective thus far
1 inexperienced spinner who has impressed, but is reliant a bit more on the other bowlers
With 3 form players, 4 players who are merely "ok" at the moment and the rest of the team out of form or ineffective any team will struggle.
The next test will see one of the "ok" batsmen replaced and one of the bowlers replaced, both with debutants. Our batting should still be ok, with our two form batsmen (Katich and Ponting) still there (you have to expect any batting lineup to have 1 out of form batsman at a time anyway - 2 is pushing it but still doable, especially with players of their class).
It is our bowling that I'm very concerned about. Johnson is in very good form with the ball, but is still pretty much new to the test match arena. Yet he is our most experienced bowler that will play. The rest of the bowlers are going to be debutants or have less than 5 tests under their belt. That is my biggest concern at the moment.
The pressure should be on the selectors for not blooding more new bowlers at test match level before now. Why has Noffke and Bollinger not had even a couple of tests in dead rubber/minnow games? Why has Siddle been picked so early and inexperienced and for such an important series?
Siddle's bowling place is guaranteed in the SCG test, which is a shame because he has not deserved it. Bollinger should have been given a run before him and Bracken must be wondering who's butt he didn't kiss to be overlooked for such an obviously green player.
