The wind could have worked against both of them. It just happened to shift at the wrong time (for Tenny). Yes. Teeny's was bigger and she started her first, but he beat her. I've seen many people come from behind. It was smart of him to throw the husk on the fire as it caused his fire to go higher.
As many times as Sam was targeted and he escaped = deserving to win to me. Rachel being better a puzzles doesn't mean she was a better player. Some people suck at puzzles. Someone throwing a rope with a ball on the end of it, to lower a ladder is also about luck just as much as it is about coordination. Kyle was a beast when it came to immunity challenges and look at what happened to him.
Rachel is deserving but I think Sam was as well. And I have seen many people cheering the fact that Teeny and Sue lost as they had been rubbing peeps the wrong way--myself included.
