The last time I saw Rigondeaux fight was when he was defeated by Loma. I know he scored a couple of knockout wins later on but I don't think he still got it. Casimero, on the other hand, is on a KO streak since 2018.
That's a good point, Casimero is one of the hottest boxers now, an underrated boxer but could win against a champion. I would also pick him in this fight, no doubt he could win and might win a KO here. The last loss of Rigondeaux was TKO because he did not continue, this could be his 2nd KO, but hopefully not in a manner he lost against Loma.
We expect a good fight, Casimero had a tougher challenge compared to Inoue... This is a statement that Casimero is not afraid of anyone, besides he is not undefeated so there's nothing to be worried about, being a great boxer does not automatically mean you are undefeated, for me, you are called great if you are exciting to watch, that's why people choose Pacquiao vs Mayweather.
