Greg Chappel was considered to be a great strategician when he captained Australia. No one could have found faults with his credentials when he was chosen as the coach of the Indian team. For some reasons, Chappel failed to rub off the Australian professionalism, aggressiveness and the killer instinct into the Indian team. He may have been a successful captain, but perhaps, he does not have it in him to be a successful coach.
Regarding Dravid, there were times when he faltered as a captain. But other captains in the past have also not made mistakes, Ganguly included. In summary, Dravid has not done bad enough to deserve another chance.
The net fall out of the WC would most likely be an exit for Chappel, while one more opportunity for Dravid. Ganguly would probably get some more opportunities as a batsmen, however, to prove that he is really back, he needs a big hundred in the next few games that he plays. Considering Pawar's announcement of harsh majors, I believe the axe will fall on Sachin who may have to sit out for a series or two. In fact, it will be in his interest to be dropped for a few matches. There will be a bit of stigma or shame attached with the dropping of the great master. But that will help him getting rid of the burden of his reputation and allow him take re-birth without any pressure of his past reputation.
By doing so, the problems of the Indian team would be far from over. If we choose new players, how much time can we give them to prove themselves? Given the impulsive nature of Indian fans, a couple of more big defeats will set tongues wagging again followed by calls for getting the old guard back.
