Matt Brown of HeavyMMA.com ranked the top 10 pound-for-pound MMA fighters in the word.

Check out his list:

10. Brock Lesnar
I know, a heavyweight in pound for pound rankings? Well, Lesnar could fight at superheavyweight and wreck people there too. He’s improving every time he enters the octagon and may very well end up as one of the best heavyweight fighters ever.

9. Dominick Cruz
Cruz (16-1) convincingly defended his WEC bantamweight title at WEC 50 by beating Joseph Benavidez for a second time. His lone defeat came at featherweight in 2007 against Urijah Faber, a fight he may get to avenge now that Faber has dropped to 135.

8. Gilbert Melendez
Currently on a four-fight win streak with victories over Rodrigo Damm, Mitsuhiro Ishida, Josh Thomson and Shinya Aoki, Melendez has established himself as the No. 2 lightweight in the world. It will interesting to see where he ends up as he is in contract negotiations with Strikeforce.
