The biggest fight since the last biggest fight is almost here. The momentum behind UFC 189 and the Jose Aldo vs. Conor McGregor title fight is so big it could easily overshadow an upcoming double main event at UFC 187 as well as a heavyweight title fight at UFC 188. All other UFC main events are beasts in their own right but Aldo vs. McGregor is genetically mutated super beast that threatens to eat all the other beasts on the island for sport.
Probably the only thing that could thwart an Aldo vs. McGregor main event hostile takeover would be Dana White riding a motorcycle leading a gang of raptors but with the dinosaur faces replaced by UFC fighters.
