As I've said previously, I attended that show.
When they first walked out, Nasser looked awesome in the standing relaxed position from the front. When they turned around, people laughed at how ridiculous Yates looked. You may hear a smattering of boos on tape, but nobody there was disputing Yates' win. He just looked better that day.
Read the show recaps - were there lots of writers calling it a fix? Where there any? Probably not. Dorian dominated and won again.
But, as usual, the judges apparently aren't as good at judging the contest as those are who view blurry pics over the internet, or were part of the world wide conspiracy to make a British native the Mr. O, since apparently there's some sort of financial windfall associated with that.
