I do agree it won't be as easy as it sound, but it seems that he is the closest that we might see someone upset Inoue, I mean Nonito try to do it, but he failed, but then everyone turns on Casimero to be the next one to try, unfortunately it didn't happen to the best weight of both of this two which is 118 lbs because we all know careless Casimero did during his reign in that division,  he missed weight and then uses sauna to shed some more weight in his second chance against Butler But that is in the past already, now he is in 122 lb and soon Inoue will also follow, and so the chance of them seeing again is there or at least for boxing fans, the hope is there.
