Lesson of Simon Biles is that it's pretty hard to call yourself the greatest of all time if you don't even participate in your competition. I suspect she just couldn't handle the hype, knew she would choke and so pulled out. I guess that's fine. If you know you're gonna fail, then at least give a teammate a chance to compete in your place. .That's the best thing she could do probably. But I don't think anyone should be calling her the greatest of all time anymore.
