Jon Jones challenges Mauricio "Shogun" Rua for the light-heavyweight championship tonight at UFC 128 in what's shaped up to become one of the most anticipated matches we've seen seen in a long time (especially for this division). Last week two great fight clips popped up on the internet, one of Jones's pro-MMA debut, and another of Rua's third match ever, against the more experienced Evangelista "Cyborg" Santos. You can see both how far each man has come, and how promising they were at the outset of their careers.
