I don't think Colby or Usman are better than Khabib anywhere. Colby isn't bigger than Khabib- one inch height advantage and doesn't look extremely cut at 170 like Khabib does at 155. Usman is worse everywhere, the only thing he has is a size advantage. I'm not convinced Usman is stronger. Technique wise, Khabib LOLstomps both them. If Khabib beats Tony, then GSP, and then beats Colby or Usman(whoever is champ) he'd literally become the undisputed GOAT and I'm a Jon Jones fanboy. Do you think he'll ever fight at WW?
