actually Tendulkar did become captain when he was young. He failed miserably and didnt get it again. But unlike smith there was never a question of the batting ability with tendulkar, lara, fleming or ponting. See what happened with ganguly, he couldnt bat and didnt deserve his place in the side and got dropped (although now i think they can use him)..
The way smith got captaincy was retarded. He didn't even make the world cup squad and then they made him captain after the world cup..For now hes doing fine and he can keep his place in the side with his batting, so no need to change things before world cup.. But well never be world beaters with him as captain. We need someone like Hansie for that......
