Thee is a reason why most of the famous basketball players and most football players are African American. They tend to be taller and have more muscle mass than other races. However, keep in mind that there are communities in India that do have the required height to compete in basketball and other competitive sports, such as rajputs and Jatts. It is these people who currently dominate sports in India.
Anyway, here is the roster of the current Indian national basketball team.

There are a couple of giants there.
Amritpal Singh: 6 ft 11
Jagdeep SIngh: 6 ft 6
Rikin Pethani- 6 ft 8
Gurvinder Gil- 6 ft 7
Satnam Singh- 7ft 2
Akilan Puri- 5ft 10
Most of them are jatts and rajputs, mostly from Punjab. Anyway, the real challenge is not geight or physique, but appropriate training and facilities, which India lacked until recently. But tbh, the US is just in a different league when it comes to basketball, because it has over a century of experience with the sport. The likelihood of another country beating it is about the same as the US winning the World Cup.
