Dhoni made mistake right from the ipl match,that continues in the T20 world cup too. I think they had given up the match when the started bowl 18th over of the last match that played against england in terms of miss fields, careless in on field. Jadeja is a good player, but he didn't play any previous match in t20 world cup,then why he had been sent by dhoni when raina went off. I think there was no intent to the players to lift the t20cup once again.
