MMA's 10 best pound-for-pound fighters

This is a big summer for MMA's pound-for-pound big three.

Georges St. Pierre was first on deck at UFC 100 and made his case as to why he should be seen as the sport's top pound-for-pound fighter. Throwing even more dirt on his April 2007 loss to Matt Serra, St. Pierre dominated another elite challenger in Thiago Alves for the balance of 25 minutes. St. Pierre's victory was so consummate that it left many wondering if it was worth his time and talent to stick around at 170 pounds.

The next move belongs to heavyweight ruler Fedor Emelianenko, who will finally square off with Josh Barnett at Affliction "Trilogy" on Aug. 1 in a bid to prove he's the sport's supreme being. A week later, at UFC 101, incumbent king Anderson Silva will have his chance to answer his fellow pound-for-pound stalwarts when he looks to add a third division of brilliance to his career résumé in a super fight against former UFC light heavyweight champion Forrest Griffin.
