Looking at the Indian ODI side, they can use this series to experiment in areas where they need to improve. No more openers batting down and middle-order at the top or new-ball bowlers coming in second-change. The position of the ODI all-rounder has to be worked out. They can have Ramesh Powar or Joginder Sharma at four (a copy of the Kiwis sending in Styris there) for some time, with Dhoni and Irfan at seven and eight. If Tendulkar is missing this series, they can use it to breed universal openers, not just Test or ODI specialists. The Test opener will have to open the innings here. One unnoticed experiment is that of using value-added bowler Ramesh Powar as a strike bowler, and that will be a massive advantage to the team. Oh yes, we'd also like to see Munaf contributing more on the field and bowling a little faster, and more of Sreesanth and RP Singh.
Then the Test side. There are complaints about Dhoni's batting, but other than that stupid incident in Mumbai, he's got a lot of potential as a frontline batsman. He needs to play for big hundreds and stay at the crease a lot longer. He's got the big shots to make up for lost time, and we saw that in the West Indies. He should be more watchful, and that's a task for Chappell. He may have his problems, but there's nothing that he can't do that a Yuvraj or Kaif can do, and neither of them can keep or bowl 20 overs. Irfan at seven may not be much, but he's certainly more productive than all the wicketkeepers tried in the Indian team for the last seven (or more) years. Kumble is no mug with the bat, and Harbhajan can spring up a surprise.
There are some advocating picking Powar over Harbhajan. While Powar adds value to the team, his performance as a strike bowler has got some experts thinking. Ian Chappell says that Powar's variations and tendency to flight the ball will give him an edge over Harbhajan, who merely thuds the ball in a little faster withlout it doing much. In recent times, although Powar has never played a Test, he's outperformed Harbhajan in ODI's they've played together, but for five wickets the latter got in one match. Besides, as the cliche goes, this is South Africa, not India, so Harbhajan may not be so effective, so that may bring both offies to the same level.
