Outside of Tibau, it was the closest three rounds of Khabib's career. Tibau got Bib when he was a child too, so all things considered, it kind of proves how great McGregor is, especially since he was a featherweight (still lineal champ) and is much smaller than Bib. I think the equivalent would be Cruz/TJ/Cody going 2-1 vs Max and then getting finished. Size is no joke, especially when you are a grappler. It is funny people consider it a horrific failure but consider other similar fights to be entertaining or honorable efforts when guys go up and do decently for a bit then succumb. The bar for McGregor is such that anytime he loses, no matter if doing unprecedented things liker short replacement fights at two classes up from his last fight, or fighting Mayweather in boxing, anything other than a McGregor first round KO is seen as a gigantic failure.
