This isn't just about entertainment, and I think some of the subtleties of Conors tactics may be lost on some who think it's just a WWE hype show.
Conor researched Khabib, his team and his family to find something that would strike a nerve.
Conor's goal of mouthing off is to make his opponents angry at him and emotional,
when it comes to fight they lose focus because so they're so emotionally invested with anger.
Does it work 100% of the time, no, for example the Diaz brothers seem to always take anger into a fight so it probably mentally made no difference with Nate.
But Poirier, Siver and Aldo all definitely got caught in that trap.
Alvarez I'm not sure it affected him as much, I think he was just outmatched.
I still think Khabib should win, but if Conor can keep pushing his buttons about religion and sketchy deals involving his team and family, then it may make Khabib more likely to do things he ordinarily would not.
Khabib is not the stoic Russian stereotype that is unfazed by talk, he clearly does not want his family or religion talked about badly.
