I've checked Kameda's losses, and he has a weak chin; he lacks knockout power to overcome Casimero. On the other hand, Casimero has been on a very long layoff. I've seen him neglecting his body when he is not training.
Is his opponent not playing it safe too? like is he aggressive? if yes, then he’s a perfect fit for casimero, and we can expect an entertaining fight since casimero loves going up against guys like that. and maybe if casimero gets his conditioning right and a bit of luck, we might even see a knockout coming from him.
