How good would Korea's soccer team be if it was the number one sport in Korea, instead of baseball? Would it be among the elite teams? Or would the corruption and mismanagement still hold Korea back?

Korea has one of the best soccer teams in Asia, but they aren't among the best in the world. Part of the reason is because baseball is king in Korea and soccer isn't that popular. So if soccer was the number one sport in Korea, would they be among the elite teams? Or would the same problems like corruption and mismanagement still hold back Korea from achieving any success?
