You’re not going to make the NHL by just being athletic. It has to do with having all the resources available to you since birth, I’m sure these ex NHL players are spending $20k + a year on their kids to play elite hockey.
Yes, hockey is a very expensive sport, plus it takes a nordic climate. I don't think you're going to see a lot of kids from the Favela become NHL players.
Athlecism isn't an automatic thing, sure it helps to have great genes but developping a body is a long term project. You have to eat well, you have to sleep well and then you have to train well.
Many of of the points made in the discussion were valid, in the end there's no simple recipe, it's a wide variety of factors. It takes dedication and hard work to become an athlete. Kids who had the exemple of an athlete at home right from the start have an advantage because they have a model to follow
Ask Brett to check with Bobby
Pavel and Valeri Bure
Eric Lindros and Brett Lindros
Brett hull and Bart Hull, Blake Hull & Bobby Hull, Jr.
(we could find so many more examples)
Similar genes, different results. Genes plays a part obviously, even if you have hockey bloodlines or not, but it goes a lot further than that. Ambition, desire, interest, dedication, training, eating, sleeping, mental health, influence, etc etc etc, so many variations will give you different results.
I think it has been brought up but for example 2 similar twins with strong hockey bloodlines could give you 2 very different end results.
