Nonito was most taller, So he get more range as compared to other people.The shorter boxer will be easy for the Nonito, he can crush the short boxer using his hand power.In addition he had a power punch compared to the Santiago.Santiago had win many old experience boxer using his power arm.This fight will against the two power arm fighter.So the game winner will be the maximum punch player.The Nonito should win the game against the Santiago to prove his power against the most powerful player.This will make them to prove his power and make other to think about the match, even this help the Nonito to get the championship.
Nonito Donaire could win this fight easily because of his natural speed and power but the problem here is if he can still manage to take punches and managed to survive up to 12 rounds of non-stop action. Because as we know, he is no longer feeling like his old self, and taking multiple power punches is way more harder than before. Most likely he will higher his chance to win when Santiago distances himself and will not gonna choose to throw multiple power punches throughout the rounds because he is scared of the counter punches from Donaire.
I wanted to think that way also, that Nonito will win this fight easy but looking at the record of Alejandro Santiago, even though he has 3 defeats, none of them are of stoppage. So we can think that Santiago is a tough fighter with a good amount of stamina. It would be easy to say that this guy can be KO'ed by Donaire easily if Donaire is still at his prime but no matter how I think of it, there is a possibility of decline of performance due to aging.
There is a possibility that Donaire can KO Santiago but I don't think that it will be that high.
Yes, he is very tough cookie to crack, I have seen his highlights as well, he is known as "Peque" because he is small but don't be deceived by it because he can really fight and this is a big opportunity for him to become a world champion.
And for sure, Santiago's camp thought about Donaire's age and maybe their strategy is to just stay in the pocket and not get knockout early. And see how Donaire's legs is. Because when we aged, specially for boxers, his legs are the first one to give in. We have seen that even to the legend Manny Pacquiao. Later on in his career, he always complains about leg cramps and most likely it is the first sign that they are showing signs of ageing.
