This upcoming mandatory fight is really a determinant factor for him what will come next to his career. Because if he wins, either he will fight with Inoue or Donaire. But if he will lose, the interest of fighting with Inoue may not come up again. As Inoue may want a different opponent that will give good ticket sales. So Casimero should really prepare for this fight because it is somewhat a reference to his next happenings of his boxing career.
Casimero's future relying on every win that he will add to his belt,
it's true that if he loses from this mandatory fight, the chance of fighting Inoue will be far to happen,
the interest will be diverted to other opponent including Butler who beat Casimero, that kind of news
will spark interest and bring more cash for the ticket sales.
If he want (Casimero) to have a much closer chance fighting Inoue, this mandatory fight
will be the best venue to showcase his skills and attract more pressure to put into Inoue's camp.
