West Bengalis are proud Indians. Why would they play for us? And also why do we even need to hire foreign players? Yes, they are Bengali but not Bangladeshi. Cricket is played by 10 countries and not 10 ethnic groups. Indian team has players from different ethnic groups be it Yuvraj/H Singh (Punjabi), Ganguly (Bengali), Sachin (Marathi), Pathans (Gujrati), etc.. and yet they play as one country. Well, foreign born Bangladeshis are different and we even have one US born athlete representing us in Olympics this year. But both his parents are from Bangladesh.
I would rather lose with 11 Bangladeshi than import West Bengalis and win.
