He is fighting against the monster, against on the top level boxer, against the number 1 in bantamweight, that's why we see the big gap between him and Naoya Inoue. This Japanese monster is just on the higher level that's why Donaire becomes nothing. Kudos though to the Filipino flash that on his first meeting against Inoue, he able to give the monster the first bad injury on its career.

Moving forward, I'm with everyone here that Donaire still has that destructive power. Of course, not against Inoue.

Going down weight class is a good move for him if the purpose is to just continue what he wants. However, in the event that he experience losing a match on that division, it's now the time to hang his gloves and enjoy his retirement. Actually according to him if I remember it right, he will really retires if he loses again after the lose against Inoue on their 1st meeting. But since he able to beat 2 opponents after that and even become a champion, he thinks he still has the power so he push on a rematch against Inoue.
