What made Sachin Tendulkar back out?

        Sachin Tendulkar had more or less agreed to take over as Test captain when it was informally offered to him last week. Three days back, he decided against it and conveyed his unwillingness to BCCI president Sharad Pawar and chief selector Dilip Vengsarkar.What happened in the interim for him to change his mind so dramatically? Why did he say no after evincing interest in the first place? Did the Board put pressure on him? Or is there a mysterious, even more significant reason, for his turnaround?We don't know yet. Tendulkar has simply said he was very happy with the way the Indian team was currently doing.However, it is not so much the present which must have weighed upon him; it is not the past as well. It is surely the future. After all, he has personally experienced the trials and tribulations of leading the Indian side, not once but twice; he has also seen the trauma some of his successors underwent from very close quarters. Maybe, he did not want to go through the entire exercise all over again.The last two years have anyway not been too kind on him. As he reinvented himself, a few of his fans felt disappointed; some experts concluded he was not the same batsman anymore; a few cynics even peeped into the future and didn't see too much of him there.But the little master-blaster overcame all those hurdles: he re-emerged as a strike force of a different vintage, the cog around which the wheel rotated. He silenced the last of his critics during the tour to England itself, coming up with heroic knocks.The stage was set for another great run in what ought to be the final stretch of his career. So around this time, when the captain's post fell vacant, it was only logical to turn towards him.MS Dhoni, for his all charisma and self-assurance, could have been a little too raw to take over this responsibility as well; VVS Laxman and Anil Kumble, more than anything else, were seen as just sentimental favourites. Sourav Ganguly and Rahul Dravid would obviously not be too keen all over again.Tendulkar, for more reasons than one, was the obvious choice. Being the total team man, he would have quickly understood the predicament before the selectors too.He surely also knew he was the best candidate in the current circumstances and might have agreed... to at least consider it. Eventually, after careful thought and weighing all pros and cons, he must have seen no point in it.Why would he want to take a risk when everything is going his way? Why would he want to do something that might harm his future, hurt his value as a brand later? After all, there is a huge difference between a great player and a failed captain.
