UFC 160 is more than a chance to watch Antonio Silva challenge Cain Velasquez for the heavyweight championship. It is an opportunity to see the precursor to perhaps the biggest MMA fight in recent memory!
If Silva takes out Velasquez and Junior dos Santos is able to defeat Mark Hunt in an undercard matchup, then the two winners, who are friends, would happily accept the chance to meet each other in the octagon. There would be a title on the line and, if there ever was a time a friendship should risk major fallout, it is over a championship. Friends have fought and fallen out over less.
