We are probably finding out just now. When Ricky Ponting picks Siddle, Hilfenhaus, Johnson and Clarke you immediately get the feeling that on a decent batting track his side would struggle to bowl out a good club side. This was apparent on a track that was deemed to be an "unfit dustbowl" when the Aussies batted at the Oval; but turned super nice for batting once the Poms had their turn. What would McGrath and Warne have made of bowling on the same track? Your guess is probably the same as mine.
The way I see things, England did not beat the No.1 test team in the world. They beat a middling team, as is now reflected in the ICC rankings. Beating the No.4 team at home was not that great a deal for the Poms; their real test awaits in South Africa later this year.
The one thing that really irritates me is how Sri Lanka managed to get to No.2 in the rankings? I mean, besides winning on sticky dusty tracks on home grounds, what else have they managed? That side is hardly a side that should be counted as the main threat to South Africa and India, but how does one work that out in the ICC rankings?
