Russian analyst Kalugin published a detailed response to Vlad Matveev's all-time UFC top 10 list, arguing that Khabib Nurmagomedov and Conor McGregor deserve inclusion. Kalugin proposed additional criteria beyond titles and defenses, including impact on sport popularization, peak performance, dominance in fights, commercial value, and records. His revised top 10 places Jon Jones first, followed by Georges St-Pierre, Khabib Nurmagomedov, Conor McGregor, and Jose Aldo. The post sparked debate about whether global influence and cultural impact should weigh as heavily as traditional metrics like title defenses and longevity in determining all-time greatness.
