One disadvantage though for Inoue is that this is a new weight class for him, and he didn't take a tune up fight, but instead he directly goes to the champion in Stephen Fulton. Yes we have seen how destructive he is in the bantamweight, but as the saying goes, maybe he swallow more than he can chew here in facing a American boxer in Fulton.
Though it could be considered a disadvantage, I see it only as a slight one. Inoue is already a destructive fighter, and he may not need to add a significant amount of weight for this new weight class. However, let's see if he can truly live up to the expectations of many, considering that Inoue is currently in his prime.
I wouldn't say that Donaire is lucky to have a rematch with Inoue, Nonito has the WBC belt that time and Inoue wanted to unify. So Donaire earn that rematch, it's not that he has been given that because of his stature. On the contrary, if you think about who is lucky, it is Inoue here because he bypass everyone in the rankings to face the champion as he move up in weight.
Or perhaps he was fortunate because he knew he could defeat Donaire, making it another easy path to claim a belt.
