May be Sachin is hanging in there just for a while, in order to make one more century. But as he continues to make unsuccessful attempts one after another, the whole century of centuries thing is becoming a joke. If it were a century of centuries in a single format then it might have been worth the wait, but scoring a century of centuries in all formats combined is of no worthwhile value, for Sachin to be taking it so seriously.
Sachin, you are a great batsman and the most loved cricketer in India. You owe it to yourself and to your millions of fans to keep it like that. Make sure not to loose it all in a desperate attempt to get that 100th century. Cricket analyst and the general public are already mentally ready to hear you call a press conference. In fact it was due right after that Worldcup final and would have added a lot of glitter to your name which is already printed in gold letters in cricket history. But now you just might be scrubbing it off.
