If performance were the only criteria, the seniors cannot be dropped now. However, to improve the team, I personally think that Ganguly has to be dropped from the side. I thought he was dropped fair and square, when Dravid took over. But now he is, in fact, playing well, and it is unfair to drop him. But something has to give way to strengthen our fielding, and he seems the weakest link of the big 3 right now.
