At 32 years old Casimero does not have the most impressive career compared to a hall of famer like Donaire. This will be his opportunity to live up to his own hype. He's been very vocal about wanting to fight Inoue and now is his opportunity to earn that fight. The height and experience advantage of Donaire will be difficult to overcome. I haven't seen odds yet but I assume most people will bet on Donaire.
Most probably, that would be the case, Donaire will be the favorite to win this fight as he is more popular than Casimero and with his recent win against Oubaali, his stocks went a little notch north.
Personally, i'm for Casimero's side here because if he wins against Donaire then Inoue would be having a hard time against him while if it's against Donaire, he would have an easier fight because he has now the experience of how the latter fight and would adjust where necessary to win convincingly.
If you look at the social media, there's a spat going on between Quadro Alas and the Filipino Flash that could fuel to this fight and somehow sell to those who are following them.
The social media spat is one sided though, it all came from Casimero, he says that:
1. When he was still a budding boxer, he approach Donaire and speaks in native Filipino, and Donaire said he can't understand what John Riel is saying. He just wanted to get a picture with Nonito
2. When Donaire started to loss fights, he saw him in the Philippines and hear him speaks Filipino.
3. Casimero at one time was being trained by Nonito Sr, so obviously the father tell Nonito if he can spar with John Riel, but Nonito Jr decline.
