I think it depends what you mean by talent entering the mix in this question. I have no doubt they are very talented golfers.So talent doesn't enter the mix?
I would have thought that would be the main ingredient personally.
But when a lot of sportsmen/women suddenly start emerging from one area it is usually due to an environemntal factor such as excellent development programmes rather than a genetic predisposition to play a sport well.
