I'm not sure if even Casimero believes this. Fulton held two world titles when Inoue beat him as did Marlon Tapales. I don't see how Casimero can be above them when he holds zero world championships and didn't look great in his previous fight against an unranked opponent. At this stage in his career the only motivation for still chasing an Inoue fight is the possibility of a seven figure payday. If we're being realistic, his chances of beating Inoue are really slim.
Well, even though I am Filipino and want John Riel Casimero to win against Naoya Inoue, I agree with you my doubt just increased after I saw his fight with Naoya Inoue's training partner that was the time when I thought John Riel Casimero was just bluffing in saying he can take on Naoya Inoue or maybe he is also bluffing that he can not handle the Sparring Partner of Naoya Inoue but for sure If he does that Naoya Inoue would never want to fight him because he doesn't have a belt that a Naoya Inoue would want,
Devin Haney is a distant 3rd for me. His win against Loma wasn't convincing. It's a tossup between Inoue and Crawford. Inoue was more active and won all 4 belts in a year. Although I consider Spence a manufactured champion who was protected from Crawford for many years, due to PBC's influence with the sanctioning bodies, he was still highly regarded. Crawford beating him so brutally gives him a slight edge over Inoue in my opinion.
His fight with Lomachenco was a banger Vasiliy Lomachenko has the speed his jab was so fast that he could surely get to Devin Haney but for sure the defense of Devin Haney was so tight and he could surely get his counter but that fight you can clearly see that Vasiliy Lomachenko is winning the fight the announcers also are shouting Lomachenko's name it was a controversial result on why there are so many strikes for Lomachenko but still Devin haney was the Victory
Inoue's camp probably thinking that Casimero is not worthy as an opponent because he was impressive on his previous fights, but during the time when Casimero was doing great, they didn't even bother to talk about fighting him, so they can't blame the fans of Casimero to think that they are just dodging Casimero.
And some people thought that Inoue is greater than Pacman, they are wrong.
Inoue is 30 years old, let's try to make a research on the fighterst that Pacman beat when he is at his 30's.
Checked his fights 2008 and below. (

probably the camp of Inoue has seen something after that fight of John Riel Casimero against the sparring partner of Naoya Inoue they are clear that Inoue is not needed to fight Casimero, as it doesn't do any great against his sparring Partner then they already think that Casimero would not be able to defeat Inoue, and that Casimero doesn't have the interest of Inoue because he doesn't have the target belt,
