Why less number of Tamils in Team sports

[manuel]

Tamils have few but important contribution in sports in india. Ramanathan & Ramesh Krishnan , amrtiaraj's in Tennis , V.Anand in chess , now Karthikeyan in motor sports and also atheletes, espesially in weightlifting have done relatively well at international levels though not super sucessfull.
On the contrary if we look at any team games like cricket or hockey , our players hardly get a chance to play, let alone prove their talent .... the only exception i find is of dhanraj pillay in hockey.
is it that lack of talent that prevents us from getting in to such field ? or is just that we are not team players.
