Jon Jones will beat Thiago Santos on Saturday night. Suggesting otherwise is an attempt to create interest and mystery in a fight in which there is none.
Santos is a perfectly fine fighter who is perhaps capable of beating anyone else in the UFC's light heavyweight division. But to pretend he earned this through anything other than being an opponent Jones has not yet decimated is silly.
If someone tells you Santos is going to shock the world Saturday, they are doing so because they want to be able to say I told you so in case of a fluke.
