So what is our goal?
1) Is it to have one top 10 singles player (men or women)? (only singles, not doubles or mixed doubles)
2) Be considered a Tennis nation?
For either of these to happen, we need a system . A system to identify talent, support players with finances, travel expenses, and coaching. With advancements in areas of sports science/injury prevention, technology, nutrition etc, even top 30 may not be possible anymore if we don't keep up. We can still maybe see a player reach top 30 (if they have this so called "freak talent" but it's going to be tough to stay there (Sania is an example)).
Something else bugs me quite a bit. What is the role of AITA? Just to organize tournaments? How about player development? Sunil Yajaman played a very important role in junior player development when he was the head of that division. Have we seen any players come up after he left (without support)? Ramkumar has support and Sumit has support.
Honestly, some of our players (Sania, Mahesh, Rohan, Vishnu, Jeevan to name a few) may not even be the best atheletes from our country. If we spot the right talent and nuture them, we can hope for better players. Yuki is so much better than Jack Sock but Jack is able to reach top 30 because of all the support that he has.
