If you're saying that more factors could be taken into account, I totally agree with you. To downplay one's competition however, is undermining the foundation of how fighters are evaluated. Not only are we looking at the UFC records of Conor and Khabib, we're looking at the UFC records of their opponents. When trying to estimate who will win between two fighters, most people fixate on their opponents to try to gauge the outcome. By going a step further and looking at the opponents of opponents, your body of data grows larger and anomalies are smoothed out. It's hard to deny that Conor's body of work in the UFC is superior to Khabib's.
Additionally, the thread is intended for those who suggest that Khabib will win based on a number of dominant performances. The reality is that he has 6 UFC decisions over a lower caliber of opponent than Conor has faced. Of this more talented pool of opponents, Conor has stopped 7 of them by TKO. I'm fine if you don't arrive at the conclusion that Conor will win based on the data that's been provided. That said, it should certainly sow doubt into the minds of those who think that Khabib is going to walk across the cage, throw Conor down, and have his way with him.
