You will be wrong.
IMO, Casimero is still a great fighter, but he's been unlucky in the past with some of his fights ending in no contest or a draw. However, I'm sure this time will be different since Saul Sanchez is not Japanese, so he won't try to fake anything like being good at acting. Also, the ref might be fairer this time, so we have a decent chance of seeing Casimero win via knockout. Hopefully, if Casimero is interviewed and challenges Inoue, we'll hear an answer of YES.
Then we'd be both happy if I'm wrong.
Casimero isn't unlucky. He was lucky, on the contrary. He was provided with great opportunities. He was granted great fights. The problem is that he wasted them all. He missed them because of sheer arrogance, unprofessionalism, carelessness, negligence, and so on.
Beating Sanchez doesn't automatically make him a worthy opponent of Inoue. Who is Sanchez, after all? Was he even a world champion? Do you think a 10-rounder victory against a nobody makes Inoue notice him?
