What magic worked for us in the WC? I tell you that is was Dhoni's brilliance that he instilled a belief in that side that they could still do a lot better and they just did.
A multi-team format where we were expected to sail until the QF for sure. In the QF we met Bangladesh who could pose any serious challenge to us. Ultimately knocked out by Australia- So, please don't go on about'some magic worked for us'- if it was magic, we ought to have won the Cup.
To elaborate further, Shashtri was given more powers just ahead of the CWC to dictate terms over a hapless Duncan Fletcher.
What could he do by staying in a series that was already lost? And he probably stepped down at the right time since India were going to have a long home season which can probably give the new Captain a lot of breathing space and give him time to figure out what works for him.
As per you, it is okay to walk away and leave the team in doldrums if the series is already lost??? By that logic, Babar Azam should step away from the Pak team and let his vice-captain take over ,cause the series is already lost. Any further losses wouldn't be on the captain's head then.
The point is, you cannot simply walk away without a proper handover. Was Kohli a part of the selection meets when the squad was chosen? If Kohli was to take ove,r you should have given him a squad of his choice, not a squad selected by that coward.
