Agree to that, doing trash talks creates attentions and that's how PPV wanted to cover,
if interest comes up from the viewers it will generate more money for both the providers and the boxers, knowing that they've got decent
shared profits every fight that promoters covered the fight. You need to build your name and create good attentions that not exempt even champions to do that to collect bigger paychecks.
But he needs to back up those talks if he cannot back it up and ends up getting knocked out, it will be a big embarrassment for him and we will become featured on many videos who about people bragging that cannot back it up, he will end up another Thurman who just embarrassed himself by too much thrash talks.
Casimero was just doing some trick to market his fight, and that is being arrogant so people will get interested in his fights, if he loses, he will be criticized but he will accept it, besides, his journey is not yet over as he is still young and he can still bounce back, but if Rigondeaux will lose, it could send him to retirement as he is not getting any younger. Rigondeaux is already 40 years old, there's only few gas left in his tank.
