Both Usman and Colby have similar fighting styles and only have 1 loss each. I don't think Usman gets the respect he deserves. He lands more strikes per minute and absorbs less strikes per minute than even Khabib. He even has a better striking accuracy and TD % than Khabib, even Colby has a better TD % than Khabib. Although I believe as of now, Khabib is arguably the greatest LW, he doesn't have as good a win as Usman beating Woodley. Usman even beat RDA worse than Khabib did. Colby is also very high-output, he attempted 533 strikes against Lawler and has tremendous cardio. Neither fighter has been dropped or KOed. I believe this is a higher-level fight than Khabib vs Tony. I think Khabib smokes Tony, Kevin Lee passed Tony's guard like knife through butter and Khabib is a better conditioned grappler than Kevin Lee. I think Usman beats Colby but it's a closer and better fight. Don't forget Tony is 35 going on 36 and has taken insane damage over his career. Both Usman and Colby are fresh and in their prime.
