> I've joked that a lot of the nerdy sports like League, Smash, speedcubing, etc. need some crazy Russian coaches.
From everything I've read about South Korean Brood War and League of Legends organizations, this thing already exists in the form of team houses where players practice for 8/10/12 hour days, and the result is that SK is head and shoulders above their competition in both games.
Of course, those games were the most popular of their respective eras in a country that values esports more than any other, and in the case of League of Legends, had massive financial support from the game developers.
You won't see something similar in Smash, where the developer isn't providing that same support and the competitive scene is dominated by grassroots communities in countries that are less gaming-centric than SK.
