Note: This list was created based on the following three criteria: Record / Resume, Achievements / Title Reigns, and Eye Test / Overall Skillset. No bias involved, these are by no means my top 50 ‘favorite’ fighters, rather who I objectively believe to be the 50 Greatest Mixed Martial Artists of all time based on the aforementioned criteria.
