this is team peroformance or any couple of players clicked that particular match that team will see the door of victory. ganguly when he taken the charge he did nothing as batsman or bowler it was dravid who won many matches, as far as test match concerned. take one day cricket, sewag now and then did well, and yuvi, kaif both did well. in 2003 world cup it was sachin who taken the team to the final with single handedly,of course i have to give some credit to srinath also. finally as a player gangu did nothing when he was a captain. if you think captainship is important even if he is not performing well, then you bring back kapil dev who succeeded at the big event and also good performer.
