I just hope that he have learned the lesson that being overconfident is also dangerous. But yes, despite that he's aware of who can he beat and win.
It's better for him to have that emotion set at the normal setting so that it won't overwhelm him when he's on another match whether it will be from a lower division fighter or of the same.
Who? Donaire? I don't really think that he have that kind of attitude where goes being overconfident to his foe because of his capabilities, we know Donaire's attitude towards Inoue though but none of it shouts that he's overconfident.
Even us didn't really expected that Inoue will evolve that much because we think that they will still have a long 12-round fight where there will be a long blow-by-blow punches all the way to the 12th round. But Inoue finished Donaire in just 2 rounds with a stoppage.
On his match with Inoue, he said that he's going to beat Inoue and that's what I think that he became overconfident on that time. That's just my opinion and if you think guys that it's not a sign that he's overconfident with those words, that's okay.
It is what I've thought of him.
But I want the best for him if he ever will have another match again. We all love to see him back and healthy again with a win.
Still not, it's not over confident, all boxers said that about their opponent on how they are going to beat them, but when the opponent happens, it doesn't mean that they are overconfident, it's that the other boxer is way better than them, (in this case, a prime Inoue destroying the legendary Donaire).
And we should factor Donaire's age in the equation, he seems to be slower now. In the first fight he lasted 12 full rounds, but with this version of Inoue, the fight only lasted 2 rounds.
