As for cherry picking, it will still be a hit for his match as everyone is waiting for his retrieval from the last lost that he has made. I'm sure that many fans of him will still watch whether it's from the organizer or his pick.
I guess there is no need for Donaire to do some cherry picking in the said division because I bet he can manage just fine even the champions in that division, he chose to fight in super-flyweight next so that means that he is confident enough that he can defeat those guys. He really knew that he cannot defeat the current Inoue now, so much better to do some cleaning in the lower weight class for now.
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.
I'm not sure if Donaire is overconfident though, yes, he has lost the first fight against Inoue, so if someone will be overconfident it should be Inoue.
Nevertheless, he didn't, he uses his speed and Donaire can't cope up with that and of course the power.
And now he is thinking to go down in weight and chase more challenges and see if he can still fight the best of them.
