Going to the olympics will be difficult for her. Germans number 3 and 5 already secured their olympic spots. And now she has to compete with Germans number 1/2 and 4 about the olympic spot.
They don't need to. USA gymnastics has an incredibly deep field of girls 20+ who are more than capable of global competition. Simone Biles is a very large tip of a very large iceberg. I don't see the US losing dominance in the next 5 years.
