If there had been a Wonderboy or Edwards , a point fighter that can inflict enough damage to make you hesitant to come in the way Khabib does then maybe that would have been a problem for him. As LW that fighter didn't exist. Justin hits as hard as anyone and look what happened.
Barboza and his KO ability with his kicks was beaten to a oulp income of the most savage beatings I've ever witnessed.
Yeah, as you know, I'm going to give these greatest of all-time discussed candidates an objective and critical run. I've said the same thing all the way through the thread about Khabib's faults/flaws, but at the same time, he is anomalous - he can fight the way he does because what he backs it up with is surefire defeat if he gets his hands on you. What is textbook to stop his stand up literally turns into hesitancy and reluctance as fighters evaluate all of their output and the consequence for throwing what are obvious, and would-be easy counters if the other guy didn't carry the threat of a superhuman maul machine.
It's quite immaterial to have sub-par stand up when it ultimately leads to what he wants, which is to get into proximity to grapple and end the fight. He closes distance in a way that nobody else is allowed to because generally, it would be suicidal to walk into, and through, established range like he does - that completely messed with Barboza's head, for example; you're supposed to go the other direction when I kick you, sort of thing, instead, Barboza started evaluating whether using his kicks was a good idea or not because of the potential consequences for doing so. Mentally, it was over.
I think the level of mental pressure he exudes and overwhelms with is bigger than his physical threat. It is clear from his fights that it doesn't take long for the other guy to conform to Khabib's style and abandon a lot of what got them the title shot in the first place. The fact he makes high level opponents not want to throw anything is akin to maybe only peak Silva, albeit for a completely different reason. It's really fascinating to watch that process of mental deconstruction.
You need someone with great stand (footwork inclusive) up as well as mental fortitude to withstand what Khabib brings to the octagon. Either that, or someone like Ferguson, who, whilst not in the tier of strikers I'm talking about, had the confidence and assuredness in he what he does to go in their and not become yet another overwhelmed opponent.
In terms of presence and aura, Khabib's the most intimidating champion I've seen - that he can make opponents so self-conscious speaks volumes for him, but in terms of names and what they've done in the sport or their ability to be the top dog, he's not got a resume like the other true contenders, imo.
Jones is still comfortably #1 for me; then the rest of the pack.
