Russian MMA commentator Kalugin published a detailed response to Vlad Matveev's top 10 greatest UFC fighters list, arguing that Khabib Nurmagomedov and Conor McGregor should be included. Kalugin proposed additional criteria beyond titles and quality of opposition, including impact on popularizing MMA globally, peak form dominance, commercial value, and records achieved. He suggested that both Khabib and McGregor made unprecedented contributions to expanding MMA's reach—McGregor worldwide and Khabib particularly in the Arab world—and that dominance in fights should carry more weight. Kalugin's revised top 10 places Jon Jones first, Georges St-Pierre second, Khabib third, and McGregor fourth, ahead of traditional legends like Anderson Silva. The post sparked discussion about what criteria truly define greatness in MMA history.
Russian MMA commentator Kalugin entered the ongoing debate over the greatest UFC fighters of all time on April 15, publishing a detailed rebuttal to a top 10 list compiled by fellow commentator Vlad Matveev.

Kalugin's central argument is that the traditional criteria of championship titles and quality of opposition tell only part of the story. He proposed expanding the framework to include a fighter's impact on popularizing MMA globally, their dominance at peak form, commercial value, and the records they achieved. Applying those additional measures, he argued, makes a compelling case for including two fighters Matveev had left off: Khabib Nurmagomedov and Conor McGregor.

Khabib, the retired Russian lightweight who finished his career at 29-0, is cited by Kalugin as transformative in bringing MMA to the Arab world. The Eagle averaged 5.32 takedowns per 15 minutes across his career, a figure that reflects the suffocating grappling dominance Kalugin says deserves heavier weighting in any greatness conversation. McGregor, meanwhile, is credited with expanding the sport's commercial reach on a truly worldwide scale.

Kalugin's revised list places Jon Jones first. Jones carries a 28-1 record and lands significant strikes at a 58 percent accuracy rate with a reach of 84 inches, numbers that reflect the kind of sustained, physically imposing dominance Kalugin's criteria reward. Khabib lands third on the revised list, McGregor fourth, with Anderson Silva and other traditional legends pushed further down.

Why it matters
- The debate forces a direct question: should cultural and commercial impact carry equal weight to titles and opposition quality in historical rankings.
- Placing Khabib third and McGregor fourth ahead of Anderson Silva reshuffles a consensus that has held for years.
- The argument highlights a genuine split among analysts over whether MMA greatness is defined purely inside the cage or by broader influence on the sport's growth.
