Why?. It may be rare for other sides, but AUS in ODIs regularly have always been able to have 3 strong ODI fast-bowlers at one time. Dont see why that suddenly wont be the case during the world cup (although Harris will be missed).
Lee is clearly back as we saw in the first ODI. Just need Johnson/Tait/Bollinger to get themselves in order for the WC during the next 6 ODIs & we will be fine.
I just think that ALL 3 fast bowlers bowling well happens way less than people think.
Doing a quick browse of the Australia games in the last 2 years and going
purely off stats, in the last 2 years I see:
v NZ Perth '09 (Tait, Bracken, Johnson)
v Pak Dubai '09 (Bracken, Hilfy, S.Clark)
v Pak Abu Dhabi '09 (Bracken, Hilfy, S.Clark)
v Pak Abu Dhabi '09 (Bracken, Bollinger, S.Clark)
v Scot Edinburgh '09 (Lee, Nannes, Johnson)
v Eng Lord's '09 (Lee, Bracken, Johnson)
V NZ Centurion '09 (Lee, Siddle, Johnson)
v Pak Sydney '10 (Siddle, Bollinger, McKay)
v Pak Adelaide '10 (Bollinger, Harris, McKay)
v Pak Perth '10 (Harris, Johnson, McKay)
v WI Melbourne '10 (Harris, Johnson, Bollinger)
V WI Adelaide '10 (Bollinger, Johnson, McKay)
V WI Melbourne '10 (Bollinger, Harris, McKay)
v NZ Hamilton '10 (Harris, Bollinger, Johnson)
v Eng The Oval '10 (Tait, Bollinger, Harris)
v Eng Lord's '10 (Tait, Bollinger, Harris)
v SL Brisbane '10 (McKay, Johnson, Starc)
That's 17 games out of 65 ODIs in the last 2 years (about 25%) where the 3 fast bowlers did well in the same game. I defined 'well' as either: 1) at least one wicket and economy of less than 5, OR 2) if economy was over 5 but they took at least 3 wickets at less than 20 per wicket OR 3) no wickets but economy of less than 4 per over. Didn't count Watson or Hopes. I was looking at how often all 3 SPECIALIST quicks did well in the same match - they don't play as fast bowlers.
You'll notice how often these good all-round bowling performances came against poor batting sides. Australia's played India, SA, SL and England 35 times in the last 2 years yet only 4 of those performances I listed came against those opponents. The other 30 games v Pak, NZ, WI and 1 each v Scotland and Ireland produced the bulk of the good fast bowling. So I think just loading up with fast bowlers and assuming they'll knock over the good sides is a mistake. There needs to be a better plan than 'we'll just stun the world with pure pace'. It'll work against Pakistan and the other lesser sides, but at some stage there is going to be good batting teams to play and they are going to handle that pace most of the time.
And for those tallying up the names, here's who features most:
9 - Johnson
9 - Bollinger
7 - Harris
6 - McKay
5 - Bracken
3 - Tait
3 - Lee
3 - Clark
2 - Siddle
2 - Hilfenhaus
1 - Starc
1 - Nannes
So it's no surprise really that Johnson, Bollinger, Tait, Lee and Siddle are the favoured 5 at present. Harris and McKay are injured. Bracken and Clark are finished. That leaves the other 5 as the top performers in the last couple of years.
