By the way we don`t have any great cpt material in the team atm. AB deserves a chance but I`m not convinced. Possible Elgar but he is not senior enough yet.. we shall see.
From my experience, captaincy material is something that players tend to demonstrate over a period of time. No one would have thought Smith would be the leader he became during 03 WC when he was entrusted.
Similarly with Smith, he came from nowhere, no one would have given him a chance.
I think AB has the right ingredients, he has the added benefit of being able to lead by his own superlative performances. The only thing lacking is on the tactical front but that what most captains learn on the job. Usually if a captain gets a consistent core group of players for about 2 years, he generally figures out his own style, and how to extract the best from his team.
Problem is the doubts over AB's future. He is only 31 but if he sees himself having at least another 5 years of international cricket, I don't see why he cannot develop into a sound leader
With Amla, I think the main reason people questioned his credentials or decision making ability is his personality, and it is not entirely unjustified. He comes across as too soft at times in interviews and in general. I have heard him run himself down on a couple of occasions, about he isn't all that as a batsman etc. There isn't really nothing wrong with that at an individual level. It's just a personality thing. Some players like McGrath or Kohli or AB like to put up a more positive or stronger show, demonstrate their confidence and their own ability. Kohli recently said he would score 2 centuries in Australia. Amla prefers to keep it simple and just let his performance do the talking, that's completely fine for Amla the batsman.
But the problem starts when he is the captain. Firstly, he refused it once so that just reinforces that perception, that he himself doesn't think he is up to it. You get the impression that perhaps his attitude or approach is not assertive enough. I mean imagine a captain speaking to his team and saying something like "yeah we are number 1 but we aren't really all that you know, there are a few teams better than us"
I am not saying he did all that. How he actually was in the dressing room, only the team can speak for it. But he gives that
impression, which is why he has to convince people that he has the decision making prowess and affirmation required. I don't think any other captain would have to make those affirmations that they can make decisions and are up to it. It's his personality working against him in this case.
