#2. Jon Jones, still an MMA god after all these years
After more than a decade in MMA, Jon 'Bones' Jones is still among the very best in the sport.
The only reason he's not No.1 on this list is the fact that he hasn't fought in almost two years. We also don't know how good he'll be in his new division of heavyweights, where behemoth champion Francis Ngannou rules.

Still, Jones' historic reign as UFC light heavyweight champion was phenomenal, to say the least. He held accolades you might only see in the career mode of UFC 4.
Most UFC title fight wins, most title defenses, and youngest champion ever are just some of his staggering achievements. Whether or not he fairs well at heavyweight, we can be sure that Jones has a very strong argument on being the greatest MMA fighter ever.
#1. Kamaru Usman, a Nigerian nightmare, rules the land
Kamaru 'The Nigerian Nightmare' Usman is just two triumphs away from tying the record for most consecutive UFC wins. If he comes out victorious at UFC 268, he'll be a step closer to legendary MMA status. That's not to say that he's not a living legend already; The Nigerian-born champion has already surpassed MMA great George St-Pierre's record of most consecutive wins at welterweight.
Ever since aligning with MMA genius Trevor Wittman, Usman has elevated his game from mere wrestler to an overall killer.
He dominated then-champion Tyron Woodley in a near-perfect performance. From there, Usman's four title defenses were as definitive as they could get.
From shutout decision wins to heart-stopping knockouts, Usman exudes an air of invincibility in the cage.
