Who is the world's best men's mixed martial artist, regardless of weight class? My latest top-10 rankings are listed below.
In addition, here are my women's pound-for-pound rankings.
Note: Results through April 17.
Plenty of "GOAT" talk surrounding Johnson following his historic win over Reis. The victory tied Anderson Silva's mark of 10 consecutive title defenses. Next up for Johnson: setting a record of his own.
McGregor made history in a historic venue at UFC 205, and he did it by channeling a legendary performance -- with plenty of showmanship. This sport has never seen anything equal to McGregor.
As far as Dillashaw is concerned, he should still be the UFC's bantamweight champion. He felt he was robbed in a decision loss to Dominick Cruz in 2016, but at least he's now in a terrific position to challenge for that title again.
Jones falls on this list, despite the fact that he has never been legitimately defeated in his career. He's suspended until July. The talent is there, but part of being a pound-for-pound best is reserving the ability to compete.
Cormier is now the owner of two UFC title defenses, after submitting Anthony Johnson for the second time at UFC 210. The Jon Jones rematch still lurks, but this man deserves to be considered a bona fide champion.
Once again, Aldo was in the driver's seat of a 145-pound fight with the great Frankie Edgar. Aldo is now 2-0 against Edgar, but he has yet to beat Conor McGregor.
Miocic enjoyed a highlight moment in his hometown of Cleveland, knocking out Overeem in the first round of UFC 203 for his first title defense. The top of the UFC's heavyweight division has been a revolving door in terms of the No. 1 spot. Has it finally found its first long-reigning champ?
Woodley finally put Stephen Thompson in the rearview mirror in March by earning a majority decision in their welterweight title fight. The fight was slow and it won't turn Woodley into a superstar, but it keeps the belt in his possession. Over the course of two fights, he spent 10 rounds in the Octagon with an unorthodox striker and emerged the champ.
Nurmagomedov has had some difficulty staying healthy, but when active, he has done nothing but win. His style appears to be kryptonite for any fighter out there, and he's fast closing in on a UFC title.
Garbrandt's rise has been nothing if not meteoric. And he's outperforming high expectations. A prospect versus prospect bout with Thomas Almeida? Garbrandt finishes it in the first round. A UFC title fight against Cruz, the best bantamweight of all time? Garbrandt schools him. If this keeps up, we'll have a crossover star on our hands.
