I have concerns about the eye which Donaire damaged. If that can hold up, the sky’s the limit. Japanese fighters have a tradition of retiring relatively young/at the right age and he’s looking fantastic now. It’s his prime. I suspect only going up too far in weight can beat him in the next 2-3 years. I love Estrada, and that’s a potentially big fight but I can’t see Estrada being too successful with Inoue. He’s too strong, hits too hard, plus has great precision and timing.
I think Inoue has already done enough to merit hall of fame induction. I think he has a shot at being the greatest boxer post Pacquaio/Mayweather given his age and the fact he’s improving. I think he’ll be considered a special fighter.
