The bowling line up was certainly in transition: when Mitchell Johnson, who at the time had played 18 Tests was the veteran leader of the bowling attack, it was most certainly a bowling line up in transition. However, their bowling
hasn't been too bad in that transition phase.
What Australia do have, is an ageing batting lineup that is in serious decline, and there's elements in the line up that need replaced, and need replaced
now. For all that Marcus North has been criticised, he's out performed Hussey comfortably since the start of that South Africa series. Hussey has averaged
35.48 in that period - and that's with 2 unbeaten tons. Ponting has averaged
42.85. They're numbers that simply aren't good enough for a team with pretensions of being number 1.
In the same period, Tendulkar averages 86, Sehwag 64, Sangakkara 71, Laxman 80, ABdV 64, Amla 56, Kallis 60, Ross Taylor averages 54 and Daniel Vettori averages 50. Australia have Katich and Watson who just sneak over the 50 mark. Even the much maligned, in terminal decline Rahul Dravid averages 57 in the last 18 or so months.
