Naoya Inoue doesn't seem like the kind of guy that avoids difficult fights. Fulton is a slick American fighter with an undefeated record. In many people's eyes Fulton is the more difficult challenge when compared to Casimero. There was already an agreement for them to fight years ago but the pandemic derailed those plans. There is a long line of fighters waiting for an opportunity to face Inoue, since he is the biggest draw in these smaller weights. Casimero has to prove that he is better than the rest in order to be at the front of the line but the weight issues and promotional problems have set him back in his career.
