Why they lost???

India beaten by Sri Lank on Friday is much of talk now. But where they failed? Why they lost? Some of the reasons according to me are,
1.Wrong selection of team: - Inclusion of Harbhajan Singh, excluding Anil Kumble despite of his performance against Bermuda. And retaining Robin Uthappa instead of taking Irfan Pathan, which would have got them an extra bawler and batsman.
2.Decision to field first
3.Giving so many extra runs in the crucial time
4.Last 5 over Sri Lanka scored 45 runs.
5.Too many experiments in the batting order
6.Failure of key players like Saurav, Sachin and Yuvarj.

There are many reasons for this failure. Surely Indian team need to find the root cause of their failure in WC07.
