Seeing Casimero heavily favored from the poll is not really that surprising and people are just waiting for his comeback since he was stripped by his WBO belt. So far, things are going well with Casimero inside his camp and I'm just not used that he's so silent since this bout has been finalized, so I assume that they're so serious inside the camp and with just a little 2 weeks left from his fight, it seems that he doesn't have that weight struggles anymore. Already excited about his return!
Anyway, here's an article I found earlier regarding Casimero's plans should he succeed in his upcoming fight.
"If I win against Akaho I want Naoya Inoue next as long as he does not run. I respect Akaho because he will fight me, he is not afraid," -Casimero said in an interview with A-Sign Boxing.
https://www.gmanetwork.com/news/sports/boxing/850209/john-riel-casimero-targets-inoue-showdown-after-ryo-akaho-fight/story/When I thought that Casimero is quietly preparing for his fight against Akaho, he had to open his mouth and then call out Inoue hehehe.
Maybe that's what really his target, I mean we have been waiting for this fight against Inoue, unfortunately he can't make the weight at 118 lbs. But since both of them are moving up to 122 lbs, this fight is inevitable.
But first Casimero should take care of his business here and beat Akaho convincingly.
Adding to your statement,even we are expecting Inoue to climb up after unifying all the belts, it's still his promoters choice if they will be ready to step up and try to win another belt with new division, I'm pretty sure that Casimero is using Inoue's name to gain more attention, knowing that it's a new division and there's still an upcoming fight for Inoue, he wanted to bring Inoue's name to make sure that fans will follow him if ever we win this fight against Akaho.
A classic Casimero, the style of hyping his fight to attract readers and possible viewers.
