Khabib vs Conor will be the biggest fight in UFC history, in term of hype, profit, PPVs etc., it's not even debattable. Conor is the most popular MMA fighter ever, former 2 divison champ, and Khabib is the undefeated LW champion, but also a superstar in Russia. Both men have the most social media followers among active UFC fighters. And yet none or them are American, isn't that surprising ? The UFC is an american company, where american fighters represent around 50% of the roster, and currently have 6 of 8 belts.
