Possibly the best pure boxer in the UFC today. Fast hands. Powerful hands. And as Mark Hunt recently learned, he kicks hard as well. Junior Dos Santos is arguably the hardest hitter in MMA. He has twelve knockouts in sixteen wins. Notable names among his victims include: Cain Velasquez (to win the UFC heavyweight championship) Frank Mir (defending the heavyweight belt) Mark Hunt (Fight of the Night) Gabriel Gonzaga (Knockout of the Night) Fabricio Werdum (Knockout of the Night, Dos Santos' UFC debut) Dos Santos probably came closer than anyone to finishing Big Country in the UFC, so add that to his list of accomplishments. Despite losing his belt back to Cain Velasquez and losing their rubber match, he's still considered the next top threat in the heavyweight division. Without a doubt Dos Santos is one of the most powerful fighters in UFC history, and definitely in the UFC today.
