Yes, barely winning wouldn't help his situation at all because he will be just viewed as a regular challenger soon enough and Inoue will be also joining him soon, so it will be a much tougher division. It will be a challenge for him of course as this is a different division and his power might have been affected by the weight climb, but let's see what he can give in this weight class.
The two champions will be surely watching on this fight because they know the noise that Casimero made and that will be an enough reason that he should give his 100% percent in defeating Akaho.
This fight will be on the radar of both champ knowing that this attempt of Casimero moving in this new division will be on chasing the title belt, they will monitoring this fight and see if Casimero will be a big threat for them or it's just another ordinary challenger, I mean, Casimero needs to make this appearance more impactful to his new weight division.
It's more likely to say that if in anyhow he will be facing one of the champ, he will have the chance to win the belt.
I think it doesn't matter if Casimero will be a threat, the champion in this division already knows that sooner or later this fighter will go up, him and Inoue. So by now, they should be prepared to go to war for either of this fighter.
And I think boxers love the challenge so they are waiting for this two to go to super bantamweight. Even those that are in the top 5 are more willing to test themselves on this two. So let's see how Casimero will be in 122 lbs, no problem in weight for him, just a question of maybe his power, but I do believed that he can bring it to this weight as well. And so the super bantamweight becomes more exciting.
Yes, I also believe that there's no problem now with his skills and especially with the weight he can comfortably move without worrying to sacrifice his diet to meet certain weight, now the only question is if his power can prove to this new division that he climb, if he will beat Akaho with a KO then the chance that he is fit with this division would likely be shown up, while if he wins by decision might be a need for him to add more trainings and drills to work out with his power punches, this is new division and new sets of much stronger opponents that he needed to fight especially those belt holders.
