Of all the fights that he had then that fight against Donaire was the challenging one for him.You could really see that he had been hit up hard and last up all rounds
which you could really see the exhaustion and tough fight for him.You could really indeed see the dedication and seriousness.He remained calm and being that too technical when it
comes on throwing punches.He always wait up for the right timing until a solid body shot or in face will surely connect out.
This fighter isnt something that could really boast off even he do knows that he do have the upperhand.
The first match was really a challenge for Inoue but the 2nd match shows a large improvement and maturity on Inoue's strategy and movement. When he beats Donaire easily, that's when I know that Inoue is capable of evolving and adapting from his opponent's boxing style and taking advantage of it to exploit the weaknesses of his opponent. On the other hand, I can't say anything about Butler's fighting style because it is too normal, and nothing special about it.
Even if we look at their second fight it is clear that this is a very big difference because Inoue really dominates and can easily beat Donaire.
He has developed very quickly and of course this is a new hope because I really like the way he fights with the speed and aggressiveness he has.
For Butler I will not underestimate him but as you said he is still ordinary in his fighting style although it is undeniable he is one of the boxers who is patient in waiting and taking advantage of the momentum but when playing with Inoue maybe this kind of patience will be very difficult to get Butler .
The level of confidence from the fans of Inoue is very high, well, we cannot blame the fans because Butler won't be a champion if Casimero was not stripped with his belt, so now, he is getting all the kind of underestimation, and hopefully he will see that as a challenge and will try to prove that we are wrong.
Just to be clear, I'm not a fan of Naoya Inoue but just referring to the close one that will happen in the match.
Even for let's say Butler is able to beat Casimero, still it doesn't change the fact that he is nowhere within Inoue's league.
People are not underestimating Butler without a good basis.
Actually regardless of the fans or not it's clear when we look at the fights and abilities of the boxers obviously this will be another consideration and I agree with you that Butler is still not in the Inoue league because indeed this could be the truth.
Even if Butler is strong but when he is in the ring with Inoue it is clear it is difficult for Butler.
