Believe that it will happen, Casimero will surely regain his name because he was not beaten through a fight. I believe the fight is going to be exciting, of course, Casimero being the aggressor is a sure thing already, his counter punching is very precise, so KO is expected this fight.
On the other note, idling for so long may affect the performance of Casimero in the early rounds. So we might possibly see a slow-starting Casimero in this fight. We have seen Loma performing like this when he has gone idle for a long time
It's on how he will prepare himself and how he will impress the fans. The goal is to win and make his way up from this new division.
His problem before was his weight, now it should not be the problem.
Definitely weight shouldn't be a problem but his stamina. I hope Casimero will improve his stamina so that he can really box it out even when the fight goes to 12 rounds. Except for Manny Pacquiao, the majority of Filipino boxers' issue is stamina. Many are skilled and strong punchers but when the fight goes a long way, many of them don't have enough stamina to stay as effective as in the early round.
