Shikhar Dhawan is a good opener and in the first test with England, we should have a good opening pair. Rohi is not there. So dropping Dhawan may not be a good idea, I feel. But the decision will depend upon many other factors like pitch condition and the requirement of the number of bowlers etc. So an opt decision will be taken by the team management basing on the conditions and requirements there. Anyhow Kohli may not venture to drop Dhawan in the first test against England, I think.
