'Khiladiyon ko bhejne ka kaam hamara hai, lekin harana unka kaam hai'is a comment I heard decades ago. Maybe even now it is true.
Except Cricket, what is the other sport or game government promote or support. I believe - hardly none. Only individuals are doing their best on their own, whether Sania Mirza or V. Anand etc.
There are tremendous scope and talended people in India who can match international players. Only govt. support and assistance is needed to bring them to light.
