Although there might be some changes when it comes to the possible opponent of Casimero, Inoue and Tapales because I think Fulton will shuffle all the cards in time when he leaves the division and vacates the belt he is possessing, if he won his future fight with Inoue.
It would be more positive for the contenders in this division if Fulton wins, as he might pursue his plan of moving up in weight class if he defeats Inoue. However, if Fulton loses, he may still consider moving up, but Inoue would hold the belts, which would make it tough for the contenders. Inoue is likely to aim to become an undisputed champion again, posing a challenge for other fighters in the division.
As for Casimero, if that scenario unfolds, he may not be easily given an opportunity. However, with hard work and dedication in all aspects of his career, he could potentially get lucky and secure meaningful fights. Winning consistently is necessary to increase his chances and make a strong case for title opportunities.
