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.
The only chances i can see for Donaire to get the win is to either control the early rounds or knock Inoue down even once and then calm down and just defend on the late rounds. I mean Donaire's style of play tends to be aggressive on the early round and then gas out on the later round, causing his punches became weak.
Inoue is known to have a destructive punches, if Donaire gas out on the later round he'll most probably gonna make that as an advantage.
That's a good analyzation you got there mate! Yes, I believe that Donaire will try to go aggressive in the early rounds and try to take down Inoue as fast as he can before his gas runs out because throwing strong consecutive punches can really take a huge gas in Donaire's tank so it's best to make that punches count and that could really hurt Inoue as that's his only choice because if he cannot make it until the 6th to 8th round then I'm afraid Inoue will take over the fight.
