+1 to what Contra is saying.
Also, as poor as Dhoni's performances have been, the coach really has to take the rap on the lack of change in team selections and attitudes.
He should have insisted on some changes when things were going wrong and he's far too late now.
18 months is plenty of time to have an impact and he's done nothing whatsoever.
It's true the coach should take the rap too but in India ?
How much is the coach allowed to do. There was a chap called Greg Chappell once who was selected as coach on the basis of a detailed document he carried with him at the time of his final interview for appointment. This was a report on what was wrong with Indian cricket from his perspective and which directions changes appeared to be required. BCCI honchos sat mesmerized as he dissected Indian cricket as if he had been an integral part of it for decades. His selection was guaranteed and he was told he would have a completely free hand.
He took them at face value and remember he was an Australian and a Chappell to boot. He started off. Treating everyone the way he would have treated international cricketers and captain in Australia, with professional deference, no less and no more. This was not something Indian cricketers and captain were used to and since Chappell had the unstinted backing of big boss Pawar, a backbiting and slimy political process started. A coterie of Indian cricketers, later joined by former cricketers some of the very vocal critics of any foreign coach and then by the electronic media which in India quickly tranates to one billion India's, made him look like a man with two horns and a pointed tail.
His fate was sealed although he became even more beligerent in the period that remained ( a Chappell and an Aussie) . So good were his ideas on what is needed for Indian cricket that Pawar insisted he take on as Chief Coach of the National Cricket Academy. He agreed but the public opinion against him was vitriolic and the first opportunity he got to leave for another assignment, he did.
So. How much Fletcher is allowed to do we don't know so I am willing to give him the benefit of doubt. Even our widely celebrated and loved coaches , Wright is case in point, right after they leave, inform us of the problems faced and the contortions required to survive and get ones points of view acted upon. Read Wrights eminently readable book on the subject.
