Kalugin debates UFC's greatest fighters, argues for Khabib and McGregor in top 10

Russian MMA analyst Kalugin responded to Vlad Matveev's top 10 greatest UFC fighters list, arguing that Khabib Nurmagomedov and Conor McGregor should be included. Kalugin contends that greatness should include factors beyond titles and opposition quality, such as impact on sport popularization, peak performance dominance, commercial draw, and records. He proposes additional criteria including geographic expansion of MMA, inspirational influence on future fighters, and era-specific commercial value. Kalugin's revised top 10 places Jon Jones first, GSP second, Khabib third, McGregor fourth, and includes Alex Pereira at sixth ahead of Anderson Silva at seventh. He acknowledges the subjective nature of such rankings while defending the importance of mainstream impact and cultural significance in determining all-time greatness.
