The same question can be asked of other small nations which dominate or excel in a particular sport.
Why are the New Zealand All Blacks so dominant in rugby union?
Why is Austria so good at winter sports?
Why does Ireland produce so many top class race horses?
In each case I think it has something to do with a unique cultural and natural environment, which then leads to the best in class supporting structures being built.
