Men's MMA pound-for-pound rankings

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 May 16.

= champion

Demetrious Johnson

1. Demetrious Johnson
Record: 26-2-1
Div.: Flyweight (UFC)
Last: W (Sub3) Wilson Reis, April 15, 2017
Next: TBD

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.

Conor McGregor

2. Conor McGregor
Record: 21-3
Div.: Lightweight/Featherweight (UFC)
Last: W (KO2) Eddie Alvarez, Nov. 12, 2016
Next: TBD

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.

TJ Dillashaw

3. TJ Dillashaw
Div.: Bantamweight (UFC)
Last: W (UD3) John Lineker, Dec. 30, 2016
Next: UFC 213 on July 8, vs. Cody Garbrandt

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.

Jon Jones

4. Jon Jones
Record: 22-1
Div.: Light heavyweight (UFC)
Last: W (UD5) Ovince Saint Preux, April 23, 2016
Next: UFC 214 on July 29, vs. Daniel Cormier

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.

Daniel Cormier

5. Daniel Cormier
Record: 19-1
Div.: Light heavyweight
Last: W (Sub2) Anthony Johnson, April 8, 2017
Next: UFC 214 on July 29, vs. Jon Jones

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.

Stipe Miocic

6. Stipe Miocic
Record: 17-2
Div.: Heavyweight (UFC)
Last: W (TKO1) Junior dos Santos, May 13, 2017
Next: TBD

UFC 211 brought Junior dos Santos, the previous man to defeat Miocic (back in 2014). It resulted in another first-round knockout. That's five knockouts in a row for Cleveland's own. Dominant heavyweight champ? Could it be?

Jose Aldo

7. Jose Aldo
Div.: Featherweight (UFC)
Last: W (UD5) Frankie Edgar, July 9, 2016
Next: UFC 212 on June 3, vs. Max Holloway

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.

Tyron Woodley

8. Tyron Woodley
Div.: Welterweight (UFC)
Last: W (MD) Stephen Thompson, March, 4, 2017
Next: TBD

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.

Khabib Nurmagomedov

9. Khabib Nurmagomedov
Div.: Lightweight (UFC)
Last: W (SUB3) Michael Johnson, Nov. 12, 2016
Next: TBD

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.

Cody Garbrandt

10. Cody Garbrandt
Record: 11-0
Div.: Bantamweight (UFC)
Last: W (UD5) Dominick Cruz, Dec. 30, 2016
Next: UFC 213 on July 8, vs. TJ Dillashaw

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.
