Not even the announcers noticed it, but if you are watching the leg, you can't miss it.
If you have access to a link, post it. Otherwise, I'll say it's preposterous to say you "can't miss it" on a peice of tape that's been watched and rewatched by lots of learned people since last weekend. None of them have reported this.

Hogwash. The horse was moving perfectly.
If he had been staggering the way you describe, he would have been scratched immediately. No rider would have been willing to go forward on a broken down horse, putting themselves at great risk. None of the other riders would have wanted any part of sharing the racetrack with a horse ready to fall down. Nobody would have wanted any part of the liability for the resulting dead or injured riders.
No one observed anything amiss with Barbaro prior to the race.
