Tokyo:Finally, it all became too much. Simone Biles felt it hours before she took the floor in Tokyo, a nervousness she couldn't explain as she waited to deliver what everyone except her was sure would be a gold medal for the US women's gymnastics team.
"I was just like shaking, could barely nap," Biles said.
"I've never felt like this going into a competition before."
Five years ago, she came through for her country with a haul of four golds and a silver in Rio. But this night in Japan with the official coronation of her Olympic greatness at stake proved one bridge too far, even for the gymnast considered by many to be the greatest ever.
Not only was Biles supposed to lead her team to gold, but to jumpstart an Olympics that is being largely ignored at home. She was facing the pressure of Olympic history while also being tasked with bringing eyeballs to primetime on Tuesday night TV to help salvage the billion dollars or so that NBC spent to land the games.

That she failed before she even started was as stunning as it was dispiriting. She had no injury and offered no other excuses before withdrawing after a poor vault in the first rotation.
Just not enough mental focus to feel she could compete with her teammates against the Russians and everyone else.
If it was shocking, it couldn't have been all that surprising. Olympic history is littered with athletes who for one reason or another couldn't rise to the occasion.
Add to that the fact that being the face of the Olympics for an entire nation is hard, extraordinarily hard.
On the same day Biles found herself unable to continue, Japan's Naomi Osaka was unceremoniously bounced from the games amid continuing questions about her mental health that prompted her to withdraw from the French Open two months ago. Like Biles, the tennis player was supposed to be her country's star athlete, and the intensity mounted when she was chosen to light the Olympic flame at the opening ceremony.
It didn't matter that there were no fans on hand to watch her lose in the third round of the Olympic tennis tournament. Eyeballs around Japan were focused on her every move, and she felt every one of them.
"I definitely feel like there was a lot of pressure for this," Osaka said.
"I think it's maybe because I haven't played in the Olympics before and for the first year (it) was a bit much."
