Casimero is only in the rank 7. If anyone deserves the shot to a title, it's Luis Nery but even him was skipped by Innoue all for unification. There is a possibility that Inoue will move to 126 lbs and probably skip all but challenge Robeisy Ramirez. After all, he already beat Fulton which is below Robeisy so fighting Fulton I think is more of a strategy to get the WBO belt from Robeisy.
Too much hype for Luis Nery. He will just be eaten alive by Naoya Inoue if they will face off. Nery was being skipped by Inoue? Definitely no. Inoue is not like that but it's om his promoter that is arranging the fight. It's just that Nery is likely prohibited to fight in Japan (please correct me if I'm wrong).
Nery is just full of talk. I don't see him a good match for Inoue.
Marlon Tapales is the most reasonable boxer that Inoue should face and it now happened. Casimero will soon catch up but to become a champion again regardless of who will be his opponent at that time.
I think Nery will be too small for Inoue though, although Nery has the power to knockout anyone at this weight, but he hasn't face a fighter with a caliber of Inoue. For me, it's better if we will see Nery vs Casimero, two trash talker and had power and see who will be the last man standing.
Inoue should focus first on Marlon Tapales, although we wanted to support him as a big underdog, but we really haven't seen a boxer close to defeat Inoue. Only Nonito was able to almost beat Inoue in their first encounter, very close fight and Donaire broke Inoue's orbital bone. But after that, Inoue level up and knockout everyone he fights, including a rematch with the Filipino Flash.
