Khabib is phenomenal, but even his Dad admits you have to go up and take out heavier champs. So far, I know this fact will trigger you, but Conor has accomplished more: first ever two weight champ, one of a handful of fighters to hold two belts at all, beat an all time great in devastating fashion during his prime, won at three weight classes in a year. Comparing those accomplishments to that of Khabib's is very hard. The bigger guy should beat the smaller guy, so the implications of 195 Khabib beating 168 pound Conor aren't as great as you think. Khabib has a lot of work left to do and needs some serious marquee match ups to get there.
