Not at all, Australia's dropping catches has happened in equal measure since 2002\03. This is simply the only time most people have noticed it, because it's the only time it's caused the loss of a series (though they'd probably have beaten India in 2003\04 but for dropped catches).
How many catches was it in the Ashes? Inbetween 12-16 I think. Now I recall Australia haviong bad days in the field, but nothing like that. If you can name a series when they did that (aside from Bill Lawry's 1969 side) then by all means tell me.
That's nothing - almost all captains steadfastly, and stupidly, refuse to use third-man when near enough a third of boundaries come down there - even more against the new-ball.
I blame Ian Chappell for that, he set that trend.
Michael Vaughn didn't. The strategy itselt isn't terrible, if it's working. Marcus Trescothick is an example of a player who can beautifully nudge the ball around and guide it through gully and slip. It worked with Chappell because he had the bowlers like Lillee who were masters at finding edges. And more importantly, he's stack the slips. I'm talking about 4th slip and gully. If Ponting did that then OK. But two ore three slips and a gully left Tresco with enough room to make runs easily. I can understand being aggressive, but after X-amount of runs have been scored, guys like Chappell would have used a third man. Ponting wasn't used to that situation and decided to keep on being aggressive. How he reacted under pressure was really interesting.
In stark contrast to this was Michael Vaughn setting a field to Matthew Hayden. Noticing where Hayden liked to hit and how he liked to bully, he put somebody at silly mid-off taking away his freedom. Tresco was free to score in the parts he liked. Hayden wasn't.
That's all well and good, but no captain, however good, can do anything at all if the ability is not there. And as such catches still went down by the truckload towards the end of Waugh's captaincy stint, when Australia's catching skill went downhill.
What? Fielding standards were great in Waugh's era. The first time I noticed the dropsies in the Aussies was in NZ. This may be hard to explain, but sometimes to concentrate more and work harder than you thought you could, you need a motivater. The Aussies looked afraid to let Steve Waugh down and looked more distressed when they dropped catches. Look at Glenn McGrath dropping his catch in the 1999 World Cup Final. McGrath himself has said he's a ruthless captain that demanded nothing less than perfection and wanted to eliminate dead rubbers. He gave the Aussies a sort of attrition, a "fall into line" vibe that made their standards in fielding improve.
Warne might've captained well in ODIs in 1998 but I can tell you for nothing, he's been a pretty terrible captain in one-dayers in England. Made all the wrong changes at all the wrong times.
You don't like his Hampshire captaincy?
