http://www.MMAWeekly.com/ -- "When my fists talk, everybody understands." Those are the words that should strike fear in the hearts of most men... especially when they are spoken by UFC heavyweight champion Junior dos Santos, one of the most feared strikers in the sport, let alone the heavyweight division. Frank Mir hasn't admitted to such a fear, however, so it will be up to dos Santos to put that fear in Mir's face at UFC 146 on Saturday night.
