No one ever said that Chael Sonnen wasn't confident. Just take a look at his own version of the UFC 148 promotional poster taken from his Twitter background complete with the "Gangsta from West Lynn, Oregon" front and center, and with the UFC middleweight title no less. Sonnen will be challenging the long reigning and pound-for-pound king Anderson Silva in the main event this Saturday night (July 7, 2012) in one of the biggest rematches of all time. Do you think this type of promotion could be getting in the head of "The Spider?"
