Debate over greatest UFC fighters sparked by exclusion of Khabib and McGregor

A discussion has emerged regarding the criteria for ranking the greatest UFC fighters of all time. In response to Vlad Matveev's top-10 list, questions were raised about the absence of Khabib Nurmagomedov and Conor McGregor despite including fighters like Daniel Cormier, Alexander Volkanovski, and Randy Couture. The debate centers on whether greatness should be measured solely by title defenses and opponent quality, or should also include factors like global impact, popularization of MMA, peak performance dominance, commercial success, and records. An alternative ranking was proposed that places Jon Jones first, followed by Georges St-Pierre, Khabib Nurmagomedov, Conor McGregor, and Jose Aldo in the top five. The discussion emphasizes that Khabib and McGregor significantly expanded MMA's reach globally, particularly in the Arab world and mainstream markets respectively.
