On test cricket they do depends on him, Everybody knows what happened in last English tour. But there are some other players already exist in the current test team who rise on the occasion time to time, already mentioned 2 examples (Rahane, Pujara) and to add one more name here, Mayank Aggarwal -- no one should forget his inning on Boxing day test match.
Rahane and Pujara are good players. But then the problem is with consistency. They fail to rise to the occasion, when they are needed the most. And Mayank Aggarwal is not even a regular in the test squad. For me, the Indian test squad still looks like a one-man army, especially in the bowler friendly pitches. But they are not as dependent as they were in the 90s, when Sachin Tendulkar was the backbone of batting.
