Insinuating that everyone always performs perfectly at the Olympics? I just watched a woman cry because she only landed a double-spin instead of a triple during the figure skating competiton. I supposed she didn't land her jump on purpose too?

Don't get me wrong, I don't believe he accidentally touched the rock, but I am shocked you find it so unbelievable that someone could be so focused on where their rock is going that they didn't pay enough attention to how their hand was positioned after they let go of the rock. High pressure situations create surprising mistakes.
