Boxing politics? yeah, purse bid is ridiculous, as a champion of the organization, they should have increased the purse bid so that it will somewhat be fair for Casimero.
That's how they see the value of the belt Casimero is holding, and I think Casimero should not mind that, what should be in his mind is to win and wait for the right timing to fight Inoue.
He might be receiving small purse in the past, but he has proven himself, defended the belt of WBO. Hopefully though, he wont' take this as disrespect to him and will go and fight Butler no matter how big or small the purse is.
He will take the fight though, no way he will just give up the belt that he work hard to achieve it, the purse maybe small for now, but once he gets a chance to fight with Inoue, that could probably be the biggest fight of his career.
