I expect there to be a string of tennis players coming out of Korea in twenty years because of Chung. They won’t necessarily be good due to the poor coaching quality there unless the country imports talent.
Chung should have a big following in Indian Wells and USO because Los Angeles and Flushing have a Koreatown and big Asian populations.
People said the same thing about Japan because of Nishikori...and yet...there's what 4 other Japanese players in the top 200 and 3 of them are the same age as Nishikori and one is older than he is by 5 years. I think if he wins a Slam or is Top 10 there's a better chance that you'll see more players out of SK trying to make it on the tour, but I'm not sure that if he's just hot for 1 tournament its going to make much difference.
