Russian MMA commentator Kalugin published a lengthy post critiquing Vlad Matveev's top 10 greatest UFC fighters of all time, specifically questioning the absence of Khabib Nurmagomedov and Conor McGregor. Kalugin argues that greatness should include not only titles and opposition quality, but also global impact, peak performance, dominance in fights, commercial value, and records. He proposes his own top 10 list that includes Jon Jones first, followed by GSP, Khabib third, and Conor McGregor fourth, also featuring Alex Pereira sixth and Islam Makhachev ninth. Kalugin emphasizes that both Khabib and Conor massively expanded MMA's reach—Khabib in the Arab world and Conor globally—and that their influence on the sport's growth should be a key criterion. He acknowledges the subjectivity of such rankings and presents his list as a friendly counterpoint to Matveev's analysis.
Russian MMA commentator Kalugin has entered the ongoing debate over the greatest UFC fighters of all time, publishing a detailed critique of fellow analyst Vlad Matveev's top 10 list and making the case that Khabib Nurmagomedov and Conor McGregor deserve prominent spots.

Kalugin's central argument is that greatness cannot be measured by titles and opposition quality alone. He contends that global impact, peak performance, in-fight dominance, commercial value, and record-setting achievements must all factor into any serious ranking. By that broader standard, he proposes his own top 10, placing Jon Jones first, Georges St-Pierre second, Khabib third, and Conor McGregor fourth, with Alex Pereira sixth and Islam Makhachev ninth.

Jones, 38, carries a 28-1-0 record and stands six-foot-four with an extraordinary 84-inch reach. He lands 4.38 significant strikes per minute at 58 percent accuracy, numbers that support Kalugin's case for the top spot.

Khabib Nurmagomedov, 37, retired with a perfect 29-0-0 record. The Russian standout averaged 5.32 takedowns per 15 minutes and landed 4.1 significant strikes per minute, combining elite grappling with consistent offensive output. Kalugin specifically highlights Khabib's expansion of MMA's audience across the Arab world as a reason his legacy extends beyond the cage.

McGregor's absence from Matveev's list is the other flashpoint. Kalugin credits the Irishman with driving global commercial growth for the sport in a way few athletes in any discipline have managed.

Why it matters
- The debate touches on how "greatest ever" should be defined — purely competitive or inclusive of cultural and commercial influence.
- Khabib's placement at third would rank him above several long-reigning champions, a position likely to generate further discussion.
- Kalugin frames his list as a friendly counterpoint rather than a definitive verdict, acknowledging the inherent subjectivity of all-time rankings.
