The Indians should take T20 seriously, and play accordingly. They seem completely misfit in T20- almost like they were in Tests in England and Australia lately. I'd prefer to see players good enough for T20 playing T20Is for India- and the likes of Tiwary, Harbhajan and Chawla don't count. Ideally, a completely different team for T20 is needed for India, for the next two years, but I don't mind having a few blokes not established in Tests (Rohit, Gambhir, Irfan, Mishra) being T20I regulars. Dhoni should quit T20Is for good, and concentrate on fixing his Test batting and keeping.
And get rid of Duncan Fletcher. We've had enough of failure under this has-been.
