Computerized All-Time Mixed Martial Arts Rankings
The all-time rankings reflect the overall careers of MMA fighters. When observing these lists, it is important to consider the following:
- All-time rankings are division-specific, whereas the current rankings are division-adjusted. Therefore, a fighter CAN be ranked in more than one division.
- Longevity at or near the top of the division plays a huge role in where a fighter is ranked. All of the rankings are career-long, with the exception of the division dominance list, which ranks fighters based on their most dominant period. Only extreme cases of past-prime bad performances are not completely excused from the rankings. Divisional strength is also a large factor in accumulating all-time ranking points.
- Head-to-head results have a minor, but direct effect.
- These rankings are not updated as often as the current rankings. Please check the last updated date at the top of the page.
- The nature of the rankings requires them for the most part, to be “slow” in reacting to actions made by current fighters. Think ‘rolling average’, versus immediate change when looking for effects from recent fights.
- Fluctuations in the position of active fighters may be a frequent occurrence. This is merely due to how these rankings are calculated. However, fluctuations may also accompany mathematical revisions or data updates.
- The all-time division dominance has minimum requirements for divisional tenure and as of 11/2012 uses the same revamped model as in the current rankings.
- Early Pancrase (pre-mid 2000) bouts were open-weight. Due to the impact of these matches, the “credit” is assigned to fighters within the division that these fighters would’ve competed in had there been weight divisions, but only from early 1997 and on (when UFC started adapting weight divisions). Surrounding data (in terms of chronology) is analyzed to determine a division. If one cannot be definitively determined, the credit will be assigned to the fighter for Heavyweight+.
