Captaincy of Strauss and Ponting
The captaincy of Ponting and Strauss is surely going to have a large bearing on the series, both in terms of their tactical ability and their ability to keep the team mentally on the right track.
They are very contrasting in styles, Strauss a lot more laid back and Ponting a lot more in your face. Ponting also has miles more experience as captain, although Strauss is an experienced and mature player.
The contrast in their styles came to mind when I just read the two lead articles on Cricinfo, with Ponting urging his players to become legends, and Strauss describing the test of character ahead for his team.
I would be interested to hear people's views on how their relative strengths and weaknesses will impact the series.
