The odds doesn't change that much, Donaire is still 4:1 underdog.
I think for underdog bettors this is really a good odds assuming that Donaire can still fight and has the power and the timing to counter Inoue when he is going inside just like in the first fight. Donaire though will need to have a lot of stamina against the young Inoue to be able to sustain his attack the whole 12 rounds because this is what I'm seeing in this fight. Back and forth war throughout 12.
Good also for bettors that really support Nonito Donaire even if they see Naoya Inoue has the better chance of winning. I will admit I like to place a bet for Nonito Donaire because there's no big reason why should I place a bet for Inoue. I will stand on my Flag and who's our representative there regardless of the odds.
Even Naoya Inoue seems to be improved since their first meeting, the same goes for Nonito Donaire too. The fact that he maintains his speed, that's already a good advantage as it means, he really worked out on that continuously. Donaire's movements are not the usual movement that a 39-year-old boxer should be supposed to be shown. That's how different he is even at that age.
