My Playing XI for Team India:
1: Gautam Gambhir
2: Virender Sehwag
3: MS Dhoni
4: Suresh Raina
5: Yuvraj Singh
6: Ravindra Jadeja
7: Harbhajan Singh
8: Zaheer Khan
9: Praveen Kumar
10: Ashish Nehra
11: Piyush Chawla*
* Or I might go with Yusuf Pathan at number 6 and Chawla out of the XI
That lineup is weak on the specialist batsman. Bhajji, Zaheer, Jadeja, Praveen can be irritatingly inconsistent. Same with Yusuf, who is always inconcistent. You dont need 6 bowlers in a T20 when you have Yuvraj and Raina as reliable backup options. I would go with Rohit Sharma (who has hit good form in the IPL) for Nehra and Yusuf for Jadeja or Chawla.
@ Pranav: Do you think Jadeja's batting has improved enough to correct the mistakes that he made in the last T20 World Cup? He doesnt connect well for the big hits, and at times he could score so slowly to hurt the side.
