One thing about Ponting- although it may reflect more on Australian cricket than on him- is that he very seldom goes into a game without a plan for each and every batsman. His problems are with thinking on his feet, that he isn't the best under pressure or that he can't come up with a plan B. But as preparation goes, there aren't many teams that do it as well as Australia.
Anyone care to try to rank the current international test captains- Vettori, Pietersen, Kumble, Ponting, Jayawardene, Malik, Smith and Gayle- on their captaincy ability? I'd have Ponting above Kumble, Gayle and Malik (not in that order), and Pietersen can't really be judged yet. So basically he's 4th out of 7- precise mediocrity.
