Right, if he wants to keep his name of top of this new division, he should come in with a bang, so his goal is to really win by a knockout. And that is what known from Casimero, so arrogant and brandish that you hate him sometimes but he delivered the goods when he was at the bantamweight, it just he fell short of fighting Butler or Inoue.
I do not think that Casimero's name will explode after defeating Akaho. As far as I know Akaho is still an unknown boxer, so defeating him doesn't mean Casimero will be on top again. If Casimero wanted to be listed as among the top contender of the Division, I believe he needs to fight more boxers and even a rematch with Tete and beat him. That maybe put Casimero to the ranking again.
But since he move up to super bantamweight, he need to be impressive and just not just a ordinary win because he is not a ordinary boxer. He has the talent and the boxer and I think he can regain back, at least one title in 122 lbs will do good for him.
I agree, a KO is a good win, or a dominating performance that will give him a mile score in UD if the fight lasted till the final round.
