About the list: All 12 members of our staff submitted their own individual 30 greatest UFC fighters list. Each fighter was assigned a corresponding numerical value based on where they were ranked on an individual’s list, i.e. No. 1 = 30, No. 2 = 29, etc. We took those numbers and added them up to get a total number for each fighter to determine the composite ranking of MMA Junkie’s 30 greatest UFC fighters of all time.
