If Trevor Hohns was chairman of the Indian selection committee, he would play both Chopra and Yuvraj, and drop Ganguly, and serve a notice to him, and also Laxman and Kumble- "Step up in fielding or stay out of the team!" I have never come across even 1 bad fielder in the current Australian teams, since 1999.
So what if Chopra has an average in the mid-20s? Is one bad series really enough to judge a player? He started off well, with an average of 46 in his debut series, so he has some ability. He is the best opener in India, not just in blunting the new ball, but also scoring runs. Makeshift openers don't work in Tests. If they want to send a makeshift opener, they can send in Sachin, because he's far more reliable than Yuvraj or Parthiv. Chopra should also play more limited overs cricket, at any level, to get into the habit of scoring quick runs. Even if he does not score too many runs beyond boundaries, he gets them between wickets.
