I should clarify my earlier comment. I think Clarke has shown himself to be a capable leader to date. Ponting also showed himself capable at times, he had plenty of good series wins and won a couple of World Cups.
He also had some poor moments I thought tactically. The worst was a couple of years back in India. From memory it was that series where Krezja made a great debut. The final test was a must win for them. They had India on the ropes, 6 down just before tea, then he bowls Krezja and a part time spinner for around 1.5 hours without getting a wicket. He said in the press conference he was concerned about the over rate and getting suspended for the first test of the Aussie summer. Yeah great work Punter, you blew that series in India mate. That session of cricket was the most infuriating I've seen in over 30 years of following the game. Just basic, dumb captaincy. Bit selfish too, which to be fair to Ponting, was not part of his normal game.
The point I was getting at about Clarkes captaincy is that I don't see him as a great leap forward. He doesn't strike me as a significantly better captain than Ponting. Time will tell though. I hope he proves me wrong and the Aussies start dominating again.
