Even so, why then do we not see great WS players from Denmark's own backyard in this current era? Marin is an anomaly.
All players that wins the world championship or olympics are anomalies I suppose...
You need two things:
1) To spot the young player with the right talent.
2) To give that player the needed help, coaching and opportunities to develop their skill.
Regarding 1), it's a matter of screening enough players, thus it become a game of numbers - the more players who play, the more raw talents you'll come by. In Spain there are not so many players, but it's not completely in the dark either. The federation is fairly new (compared to the "big four" in European badminton, Germany, France, England and Denmark), but they are gaining traction and now have 8000+ registered club players. Still only a 10th of Denmark, but not as bad as many other countries (Poland, Norway, etc.).
Regarding 2), it's a matter of tradition, knowledge and resources. Here Carolina Marin has been helped the best possible way. She's won numerous Spanish championships (including senior championships as a junior), and they fairly quickly organized a "Team Marin" around her, hiring in help as needed. She probably have had better surroundings in terms of resources, etc than most other big badminton countries top players.
All in all, her performance at this young age is nothing short of fantastic. And the ceiling seems to be high, in terms of what she can continue to achieve. It's highly unusual to see such talent from a country like Spain, but they have really taken her talent serious and pulled in the needed help.
-----
When she was injured, she trained full time with her coaching team, trying to improve tactics, strategy and reading opponents. They had a projector setup in the arena, analyzed her opponents (thoroughly) and quizzed her towards shot selection, prediction, tactics, etc. She practiced and practiced (while injured remember) in order to learn "by reflex" where and how to play, in tough situations against her most fierce competitors.
I've heard a lot of players and coaches say, that other athletes (including those from other sports) could learn from Marin's work ethics and structured approach. It's not all just luck and coincidence you know.
