It's because of the junior programs they have nation wide. It serves a double purpose. It gets kids into sports of some/any sort so they mightn't grow into bloody obese monsters, as well it helps the higher level programs identify talent at a young age, unlike here were a fabulously talented athlete can go from cradle to grave and never be noticed. Once a shining young star is identified, they are groomed and taken care of by the state sports associations so that said young star can shine brightly for their country, if they wish. Here in Canada, we expect our athletes to become world class while holding a day job, paying for coaches and gear out of pocket, and then do us proud after we ignored you your entire life. Not surprising some jump ship. Imagine if that grassroots level of interest was shown in our athletes. We would seriously kick ass.
