Russian MMA commentator Kalugin published his subjective top 10 greatest UFC fighters in response to Vlad Matveev's rankings. Kalugin argued that Matveev's criteria overlooked critical factors like global impact, commercial success, peak performance dominance, and contribution to MMA popularization. He specifically questioned the absence of Khabib Nurmagomedov and Conor McGregor from Matveev's top 10, despite their massive influence on the sport. Kalugin's revised list includes Jon Jones at number one, followed by Georges St-Pierre, Khabib Nurmagomedov, Conor McGregor, Jose Aldo, Alex Pereira, Anderson Silva, Demetrious Johnson, Islam Makhachev, and Amanda Nunes. He emphasized that greatness extends beyond title defenses to include factors like inspiring future fighters and expanding MMA's geographic reach.
Russian MMA commentator Kalugin entered the debate over the greatest UFC fighters of all time on April 15, publishing his own revised top 10 list as a direct response to rankings put forward by fellow commentator Vlad Matveev.

Kalugin's central argument was that Matveev's criteria were too narrow, failing to account for global impact, commercial success, peak-performance dominance, and each fighter's role in spreading MMA to new audiences. He singled out the absence of Khabib Nurmagomedov and Conor McGregor as particularly glaring omissions, contending that both men transcended the sport in ways that title defenses alone cannot measure.

Khabib Nurmagomedov, the 37-year-old Russian lightweight who retired with a perfect 29-0-0 record, slots in at number three on Kalugin's list. Standing 178 centimeters tall with a matching 178-centimeter reach, Khabib averaged 5.32 takedowns per 15 minutes across his career, a suffocating grappling output that underpinned an unbeaten run and helped inspire a generation of fighters from the former Soviet states.

Topping the list is Jon Jones, the 38-year-old American who carries a 28-1-0 record and is widely regarded as one of the most physically gifted fighters the UFC has produced. At six-foot-four with an extraordinary 84-inch reach, Jones lands 4.38 significant strikes per minute at a 58 percent accuracy rate, combining elite striking with 1.89 takedowns per 15 minutes.

Why it matters
- The debate highlights ongoing disagreement over how greatness should be measured in MMA: title defenses versus cultural and commercial impact.
- Khabib and McGregor's inclusion reflects the argument that geographic reach and mainstream crossover are legitimate criteria alongside in-cage performance.
- Kalugin's list, which also features Georges St-Pierre, Jose Aldo, Alex Pereira, Anderson Silva, Demetrious Johnson, Islam Makhachev, and Amanda Nunes, spans multiple weight classes and eras, broadening the conversation beyond the traditional pound-for-pound framework.
