One of the arguments that will never be settled is over the world's best pound-for-pound fighter.
With so few fighters who possess the ability to fight in multiple weight classes, the P4P debate seems to rage on no matter what accomplishments these great champions seem to achieve.
With the talk of a P4P super-fight between George St. Pierre and Anderson Silva still in the stages of infancy, we will have to stick to lists, rankings and debates about who the best P4P fighter is. However there are multiple champions and fighters in the sport who have earned the right to throw their hat in mix so to speak. In this list we will take a look at who some of the top pound-for-pound fighters in the world are today and who may lay claim as the top P4P fighter in the near future.
