I usually like his break downs but most of his predictions never come true and you can go back and watch all of his analysis in the past, there is no ring rust for Khabib, he is not known as a party animal who goes out of shape if he is not fighting, he always spars even if he is not fighting and that is his life style and you cannot match that, he is a complete animal unless there is a freak knockout i do not see Dustin defeating Khabib, i see him mauling in the first two rounds and then he might stand up with Dustin for the third round and then go for the submission.
I don't really listen much to anyone's prediction, it was the breakdown that I commended. I'm not sure about having no ring rust at all, I believe it's always there. It's just that some fighters like Nate Diaz are really good at shaking it off quickly. There is no doubt that Khabib is a beast and his MMA record clearly shows that but, as you said, a perfectly placed punch from Dustin can end that perfect record of his.
