Fulton should rematch Figueroa, or try for the undisputed fight against Akhmadliev. I think Akhmadliev is the best at 122. Maybe the winner of the undisputed fights Inoue after he has fights against Casemeiro / Donaire II at 118.
I would much rather see both guys become undisputed in their own divisions first. Give me Fulton vs Akhmadliev!
Inoue fights and beats Casimero and Donaire to become undisputed at 118, and Fulton becomes undisputed at 122. Then Inoue fights and beats Fulton to become undisputed at 122, and retires undefeated. 4 weight world champion Undisputed champion in 2 weight classes First ever fighter at BW to hold all 4 belts That'd be quite a resume, especially for fewer than 30 pro fights.
That would be a very good resume and would make him the second greatest Japanese boxer. I don't like how you assumed Fulton would beat Akhmadliev. That's not guaranteed at all.
Fulton vs Akhmadaliev and Inoue vs Casimero, for me, winners are Akhmadaliev and Inoue. In Akhmadaliev vs Inoue, I'd favor a close decision for Inoue after he picks up and wins 10-12. In Fulton vs Inoue, I think Inoue KOs him somewhere from 9 to 11.
Right now Harada for sure has the best win, and Ioka probably has had the best career overall. Imo at least.
Eventually you hit a wall when you keep rising up in weight. Other than Pac, haha... That said, not sure if its the weight or opponent that would do it.
Inoue has the class to do this in style Not normally a huge fan of minimum weight boxers, but he is the real deal and has everything what it takes to dominate the sport
