For Sports (other than Body Building and Boxing probably) you don't need too much muscles (Indian tribes & warriors - kshatriyas were consuming meat anyhow) Especially for a game like cricket you actually don't need muscles, you just need athleticism & endurance+concentration in heat & cold! Indian tribes had perfect skills for that! What is there in cricket? (apart from technique, I guess DK & co know what's those techniques, but they just can't apply isn't it?) Indians are educated now (then, ever) I think you & the whole world agrees that! Add to that the old Indian tribal body (or even the current Indian tribes who are not disturbed with noodles, steroid milk, etc + if you are able to educate them) you will get the desired results! All you need is throwing capability at good speed (educating that to convert into bowling) After that its all skills (we have a lot of skilled players in cricket in India, its just about the combination, the full playing XI). I still remember how Australians were praising Indian batting (Laxman, Dravid, Sachin, Sehwag) in that golden period, they told that they bat like doing meditation!
So its all there, we need to just get everything in the right place! Throw out DK (I guess he is an upper caste guy, please note that I am not bringing any casteism here if you understood my actual intent! Today caste means getting more benefits in the society & becoming more powerful politically) there could be a proper athletic ancient Tamil tribe there who could do wonders (the genes could be similar to the great WI players of 70s and better than artificial steroid-based modern food Australians!)
I don't think we need to go that deep to get the perfect team (I think it is out of scope here) If we get few things right like selection, coaching, captaincy, application, etc, then we will do reasonably well...
