We also have to consider the quality of opponents Casimero has face in the past as compare to Akaho.
Akaho has failed in this two world championship attempts, while Casimero has been tearing the bantamweight leading to the failed fight against Paul Butler. And John Riel is the younger of the two, the road warrior but obviously the experience goes to Akaho as he has been professional boxers for 17 years as to Casimero's 15. But again as I have said, the key difference is the opponents that they have fought and so I think this is the big advantage for John Riel Casimero to win impressively.
That's the only advantage I see on Akaho, but overall, maybe 80% advantages goes to Casimero. I hope he is still the same, the hunger to win should still be there so he will beat Akaho impressively, the best way to win is via KO and that should be his goal in this fight.
