There is still mathematical probability for India to reach Semis. But though I am a die hard fan I would want India not to reach it because if you cant handle short pich stuff then you are not a good enough team.
If dhoni or someone say that the pitch is not in their favor and they haven't had the luxury of playing in these kind of pitches in India then I would say - that is why this is called international cricket not domestic cricket.
Reasons For Poor Performance
No fast bowling all rounder
No Genuine Fast Bowler (We did not bowl many short pitch balls while the opposition was banging us)
Pathetic performance by Ravindra Jadeja, Yusuf Pathan....
Out of form Players (Yuvraj Singh, Gambir)
Many Lottery Players (Again Yusuf Pathan, Murali Vijay, Raina)
Should have provided chance to R Ashwin or Ohja
Over Hype team
About Tendulkar - No one wanted him in 2007 when his performance was not that great. May be from that time he did not want to take part.
