We are sure Duncan must have discussed these flaws in the team meeting every time our top order batsmen fell like a house of cards and must have worked with them in the nets too.
If one looks at the dismissals in the just concluded test series, he/she would notice that most of the time Indian batsmen kept feeding English fielders with dolliest of dollies catches in the slip cordon.
There is a saying old habits die hard. True….the Indian cricket is played, learnt and nurtured on wickets that are slow and almost dead as far as swing is concerned. Its not for nothing that Indian batsmen get most of their runs on deliveries directed at their pads. With no swing and bounce, they very stylishly and easily dispatch them for runs without any problem.
