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.
