Changes have already started happening. They have already removed Dravid as a coach and a new name should be announced soon. Rohit Sharma got his chance and royally screwed it in the T20 world cup and after this humiliating defeat from Bangladesh he might be dropped as a captain for ODI squad. The same thing might happen to KL Rahul. I am still confused as to what might be the reason of Sanju Samson not being played again and again. They should have given him an opportunity. As for Kohli I think he should take a permanent rest from cricket. He no more suitable as a batter for any form of cricket.
Rather than giving the role of captain to oldies such as Rohit, the BCCI should consider some of the younger players such as Shreyas Iyer or Rishabh Pant. And regarding Sanju Samson, enough chances were given to him but he failed to utilize the opportunities. There are other keeper-batsmen in the bench such as Ishan Kishan and Shrikar Bharat. Why always Samson should be given the preference over other keepers? Let Samson perform in the India A and domestic tours first. He is yet to show the match winning capability at international level.
