Munoz has a good shot at pulling an upset, he is a genuinely nice guy and i cant help but support him, WAR MUNOZ, FILIPPINO!!!
If Munoz' wrestling is as good as all his training partners say it is and can negate some of Chaels strength in that area - its certainly not inconceivable that his heavier hands find a way to win. I still think Sonnen will UD him though.
What can I say other than styles make fights. You know this.. Do I need to draw you a map of who lost to who?
