I mean Khabib is an amazing champ n all but he's very human.
Dustin may have been far from securing that choke but he wobbled him quite a bit.
Also for someone like Dustin to even remotely come close to choking or knocking Khabib shows that Khabib might not be in his prime prime anymore.
Tons of training, tours, lots of fights... he might not be as hot as everyone thinks at the moment.
Tony on the other hand relies on being batshit crazy so I think he should be the slight favorite in this fight.
This is a Fedor-Werdum type of situation, with Fedor being a bit more out of prime than Khabib is right now and Tony being a bit more insane than Werdum was. But the body types are those.
