Well i believe that there can be some things in our genes that makes us bad for sport. For example Chilean people are in average shorter that the world average. Average high in Chilean males are 172 cm and Argentinean is 176, so they have much more percentage of mens over 180cm, wich is a good height for a defense in soccer. And also the Argentina’s population is also bigger so they have much more people that, in terms of height, are good for a soccer defense or goalkeeper so in terms only of probabilities they have the advantage.
But I believe blame our genes is a really mediocre thing, because in Chile the federal agencies nearly never help the sports, there are a lot of dark things involved like “pitutos” and greedy so the main guilty of our bad performs is sports is the government and the lack of help to young sport players.
For example China’s average mens height is 166 cm, but they have invested a lot of money in sport, and now they are in number one in gold medals in the olimpics.
In Chile some time we are good for individual sports, because all you need is a person with a lot of skills and a wealthy family to turn that boy or girl is a successful player. That happen with Chino Rios for example.
Another trait with Chilean that can explain the bad performance in sport is that the young people don’t have real discipline compared to other races like Chinese and a good example is the football player Valdivia, wish has a great talent but is such a moron, but can be solved with a very good guidance like Marcelo Bielsa, that I guess it was admired for the players and impose this father-like figure that I believe is good for the soccer player. Borghi in the other hand is like a friend, a good guy that likes Barbecue and is really funny.
