I don't see Butler be a big threat to Casimero, and nor is Graballo to Donaire, the three Inoue, Casimero and Donaire are the elite in their division I see them disposing of their respective opponents, if the two successfully defended their crown, the boxing organization should not ignore the clamor of the boxing community, we want Inoue - Casimero or Casimero - Donaire, I hope nothing unexpected to happen like an upset.
