I easily think Dhoni should NOT be made a captain for now.
Firstly because, he is too young and yet to learne some things and
secondly, he himself should not be made so assured of a spot in the team yet as karthik can open and keep, that makes a spot open for a full time batsmen or an extra bowler to come into play which is very important if India is looking to be number 1 in test ranking.
Kumble's Case:
He actually deserved it a long back and never made. It is not as if he lacks leadership or is not a strong personality. Atleast he deserves such a reward, if nothing else, for his service. And he wouldnt mind, this being stop gap.
Laxman's Case:
He was always groomed to be a captain and has done and lot of work so can also be a good prospect. But his personality is a bit softer and he allows people to think that he doesnt have a permanant spot in the team which is causing to come in the way of him becoming the one. None the less at this time, would be a great booster for him, since its australia which is coming up (after pak) and he definetly is a permanant fixture there.
Other Cases:
Definetly Gunguly shouldnt be ruled out since this is only a stop gap. Winning against australia is vital so if it needs a tried and tested one so be it. So he should be considered with an air or forgiveness and a chance to redemtion.
