ok... hate to get involved in this again... He is an excellent motivator, an excellent team mate, an excellent senior player to have around. And he is always full of ideas and tactics and is, as such, a great guy to have as vice captain or simply as a player in your side.
But captaincy is also about selection... He has failed waaaaaay too often in that regard. And if you want to know why India were so poor when he was captain, have a look at some of his selections. It is pretty much a proven thing that he doesn't have the best eye in terms of spotting talent. Nilesh Kulkarni, Jacob Martin, MSK Prasad, Abey Kuruvilla, AA himself, the list is rather long......... I am not saying he is the worst, but he is not as good as a Sourav is or an Imran Khan was. In fact, the same could be said of Dravid. Both of them don't seem to have the best eye when it comes to spotting talent.
