She lost all momentum and at least .75-1 sec in her semi and she still wasn't going all out. She is pissed and that's a good thing, if she IS NOT injured from that near fall (sometimes adrenaline always you to finish before you notice something wrong) than she's the favorite for Gold.
The way she walked off the track without being interviewed shows she is pissed. Good Athing if your healthy show them this is your event and you don't clip the defending champ. Go sub 1:55
