Jon Jones: Say what you will about his lack of one-punch knockout power, but Jones is a very dangerous entity on his feet. Blessed with ungodly physical dimensions and the athleticism to back it up, the pound-for-pound greatest fighter on the planet can land some of the most unseen techniques in the sport today. This includes spinning backfists, oblique knee kicks, standing elbows and relentless knees.
Alexander Gustafsson: Gustafsson has all the tools in the world to one day be the light heavyweight champion. He's tall, technical, persistent, versatile and capable of inflicting massive amounts of damage. Once the rest of his game rounds out, "The Mauler" could be unstoppable.
Rafael Cavalcante: Sure, guys like Dan Henderson, Glover Teixeira and Wanderlei Silva could have landed here, but hear me out. In 12-career victories, "Feijao" has recorded 11 knockouts. That's a staggering rate for anyone, let alone a Brazilian jiu-jitsu black belt. In any case, Cavalcante's power is legit, and UFC light heavyweights are about to figure that out the hard way.
