That's a bit of an overstatement for a player who has trouble keeping his place in the playing XI, don't you think?Kaif is still a good fielder and is being said of as a future captain of India.
Most likely Sehwag will succeed Dravid as captain. I would like captain with a better 'cricketing brain' than Sehwag, but I am not sure who else in the Indian team would qualify.
Certainly, SRT has the brain but his age is almost as much as Dravid, and they will likely retire soon after one-another.
So after that, my money is on Sehwag. There is virtually no one else with a set place in the XI that's would even be considered.
But this discussion is a couple years away, so maybe someone will come out of nowhere.
