If we combine all of our ideas of how Donaire can win against Inoue is just to avoid the body punch. Donaire can stand against the punch of Inoue and avoid power punches. And, I think he will stand against him if he tries to close in a fight and do left and right hooks.
As I predict the fight, it might be the same as last 2019. Donaire just needs to increase his stamina and speed since Inoue is much younger and has more speed and power.
Body punch is the signature of Inoue, Donaire was a victim in the first fight although he was not KO after getting hit by a solid body punch. I'm pretty sure Donaire are aware of it already, he already felt the power of Inoue, so he will be careful in this rematch and will try to be quicker, and also quicker to score a KO as that's his only chance to win.
Donaire cannot honestly deny that he was really lucky enough that he didn't got KO'd after Inoue gave him that solid body punch, he surely felt that punch while Inoue was also hurt but he managed to shake it off. Not just Donaire but both of them will be careful enough because they are aware of the consequence if they caught unguarded as they both know how strong they are.
Both will for sure, they already taste the solid punches against each other and now that in just one careless move their opponent can beat them up, looking to see the same type of tempo. How they fought before shows how eager both fighters to win against each other, and since this is a rematch and both of them hold belts that in stake.
More aggressive but smooth attacks to be sent by each fighter, even Donaire is underdog here, betting spare coins would be fine
to show my support for him..
