Of course, Donaire will take it seriously as he can't afford to lose the opportunity to have a rematch against Inoue, if he loses, I doubt Inoue would still give him a rematch when he doesn't have the belt anymore, it will be Casimero vs Inoue if Casimero would be successful in defending his belt.
Donaire still has it he doesn't have a long lay off and he is still fresh in his win against Oubaali he can take that momentum to this fight against Graballo, Donaire is so good in his counterpunch so we will see those counter punches against Graballo, but we cannot underestimate a fighter like Graballo who can hurt his opponent and I even saw some of his fights where he knocks out his opponents with one single punch, this guy is dangerous.
Yes as comparing to Casimero or Inoue (In which supposedly His next opponent ) Reymart Graballo is far from them and Donaire can Easily beat this one in this fight. maybe this is just a prefight before the main one next year as Casimero is also facing different opponent with Butler.
Actually what i was waiting is in Whom will Inoue be facing in the sooner time.
Others are just disappointed because they only know the names of Donaire and Casimero. If they really idolize these boxers then whoever their matchup, they should just accept it. Both Donaire and Casimero just need to win on their respective match so that they can arrange again the cancelled fight between them or possible against the top 1 Naoya Inoue next.
It's also best to see that other PH boxer is on the list. Let's support them all.
That is the best observation because Boxers may face different opponent depend on which will be given for them by the association .
