HBO doesn't like his non-crowd-pleasing style, and have openly said that they will not put out any money for his fights. You take HBO out of the equation and a fight with Joel Casamayor is worth nothing. You got to give it to Casamayor he is despertly trying to get big name to fight him.

If you remeber it was origninally going to be Joel Casamayor vs Frietas in a lightweight unification fight, until HBO would'nt buy the fight. So Freitas dumped Casamayor and got Diaz.
