There's a common adage in MMA that says that, when it comes to aging fighters, power is the last thing to go.
Former UFC heavyweight Junior dos Santos is evidence of that fact.
For many years, Dos Santos stood out as one of the best heavyweights in the world, and he might have been the best outright were it not for the existence of Cain Velasquez. During that period, he produced a slew of vicious stoppage victories over the likes of Fabricio Werdum, Stefan Struve, Mirko "Cro Cop" Filipovic, Gabriel Gonzaga, Frank Mir and even one over his two-time foil, Velasquez.
Dos Santos has slowed significantly in recent years, but his recent knockout wins over Derrick Lewis and Tai Tuivasa are the proof you need that, even if he's losing a step, he's still got fight-ending pop in both hands.
