Go back to watching NBA. Everything from your username to your shitty hot takes exposes you as a newbie fan. It's ok to be a noob, but you should just sit down, shut up, and catch up on the sport instead of mouth-shitting your terrible opinions all over this forum
Conor got an instant rematch against Diaz because
A) Conor was champion at the time and undefeated in UFC before Diaz, so he got some special treatment. Conor was ranked higher than Diaz at 155 and it was just a money fight. He was still their 155 pound champion, an active fighter, and #1 draw. The UFC HAD to allow Conor a chance to save face against Nate Diaz
By the time Khabib was champ things had changed. Conor had gotten humiliated by Mayweather, had vacated his belts, and had gone full-on diva. That is how leverage works in this sport, when you're on top you have it, when you're not on top you don't
This is the harsh reality that Conor fanboys have to face, that Conor can also be treated like just any other fighter. He never defended his belt, so he rightly doesn't deserve an instant rematch. He's a part-timer, so he doesn't get to skip rankings and get a title shot by beating a washed-up Cowboy at 170. That is how MMA works for everybody else, and now for Conor as well
Nate getting a better win over Conor than Khabib? Not even worth arguing against
