The Winter Games are primarily made up of sport Americans aren’t interested in. When a population isn’t interested in a sport their best athletes don’t play it, when the best athletes don’t play it the country does poorly in international competition, which helps retard interest in the sport. We stink at these sports the other 3 years too.
Plus there’s been a lot of disdainment for the Winter Games, with stuff like #WinterOlympicsSoWhite
That’s why the USOC went out of their way to try to have a team that “Looks Like America” instead of sending our best, and well, you see the results.
