The vice captain in Indian cricket is an interesting animal. It surfaces in overseas tours and multi-lateral tournaments. It is generally unseen in home series. For tours it has been either the most experienced player besides the captain, or the next best player and someone who is sure of his place always in the starting XI.
Dhoni is the captain for the foreseeable future but who should be the deputy for a long term? If the selectors were to look for a succession plan, the next generation of cricketers are to be considered. Run through the following names of cricketers who are the gen next to the Dhoni/Yuvraj crop - Irfan Pathan, Dinesh Karthik, RP Singh, Rohit Sharma, Raina enough already. None of them is a shoo-in for all three versions of the game and each of them has his own problem(s) to worry about. Gilchrist was gushing about Rohit's leadership in the IPL, but the Indian team is a very different beast. While Irfan P and DK strike as future possibilities, they too are not sure starters and hence in the present scheme of things just cannot be.
So much for succession planning. So the VC has to be an experienced guy, from the Dhoni/ Yuvraj crop, possibly senior even and perform the kind of role Dravid did and what Sangakkara used to do until recently - Contemporary of the captain, may not have a similar long tenure, but experienced leader and will slot in without trouble.
Sehwag and Yuvraj obviously fit in here and Sehwag is the first among equals. He is as street smart as anyone else and there is not much against him except an apparent laidbackness. Yuvraj did not seem too inspirational in both the IPLs. In fact in the first version Jayawardene and Sangakkara were running the ship in tense situations. When Dhoni was chosen over him, there was the impression that he was irked, but now he seems to have made peace with the reality. He must be allowed freely to do what he does best - that is singlehandedly win matches for India.
As for the rest, there is Zaheer, Harbhajan and Gautam Gambhir. Appointing Harbhajan in any kind of leadership role would be the biggest practical joke the selectors can play on the team, its supporters and Harbhajan himself. Gambhir is young enough to serve for another 7-8 years. He is a sure starter for all versions of the game, looked in control in his IPL stint (unlike Bhajji and Yuvraj) and has grown in stature by virtue of his performances and will hence command the respect of his peers and juniors.
For me though, Zaheer is the most impressive canditate. He took the leadership role in the field during power-plays in ODIs, mentored Ishant, set fields with great effect, importantly looked in control. Lastly, he has the respect and trust of the main man in charge. He would command respect by being a sure starter, a match-winner and a man who has fought his way back to the top by hard work and performance. In his comeback avatar, he has made himself counted with the bat more often than not showing the willingness to hand in there. In close test matches in the recent past, the resoluteness of the Indian tail has tilted things their way. Zaheer has contributed to this in a big way.
So all things being equal, Zaheer it has to be for me as VC, till the next generation stands up to be counted.
