By Ian Ransom MELBOURNE (Reuters) - Basketballer Patty Mills will don the green and gold of Australia at the Rio de Janeiro Games but gained inspiration for his third Olympics in the red dust of his country's vast, empty heartland. The first indigenous Australian to win an NBA title, the San Antonio Spurs point guard will hope to blaze a new trail in Rio by becoming the first to win an Olympic medal in the sport. Mills took the Olympic squad on a tour of the rock which is sacred to local Aboriginals and was the first Australian stop of the torch relay for the 2000 Sydney Games.
