What do mean by fit? Physical or mental? If it is physical fitness, have ever heard injury to Dravid? probably, Dravid is one of the fittest players in the world cricket today. If you are talking about mental fit, how can you evaluate this? Being a captain also he is scoring better, he knows how to deal with youngsters. You just cant demoralize his in just 2 defeats. At present, Dravid only deserves captain's position.
