The rematch between middleweight champion Anderson Silva and top contender Chael Sonnen at UFC 148 on Saturday at the MGM Grand Garden Arena in Las Vegas has captured the imagination of the mixed martial arts community. The two rivals will duke it out for a second time, a little less than two years after Silva submitted Sonnen with a dramatic fifth-round triangle armbar at UFC 117.
The subject of mental toughness in MMA surfaced on the Sherdog.net forums this week, not surprising when considering how much play the Silva-Sonnen showdown received.
