And I also think that Jake Paul vs Khabib is possible too. There was an interview where they asked Khabib about fight between him and Jake Paul. At first Khabib said that he isn't going to fight and has retired but then when he quickly realized that it was Jake Paul and he would get tons of money, he later said that we can think about this. Khabib is not as honest and ideal man as he seems from outside, he loves money too and tries to mask that. So, I would say, fight between them is possible!
It is indeed, he would be more embarrassed to himself if he gets defeated by someone who is making his debut and this is his sport where he have a vast of experience and wins in his career. Thinking about it, I don't know what would be Nate's situation if that happens but surely, he needs to expect that Jake Paul will not let him forget that knowing that the man is very vocal about his wins and achievement in life.
And that Nate vs Khabib fight? I don't think that is possible, he might've been cornered when he was asked about that because I believe that he will follow his fathers legacy just like he said and will be alongside Islam, and will not step foot in the octagon as a fighter. But if he's dazzled for the money, then I guess you're right, he's not that man we thought he was.
