Those dudes would eat Donaire alive. Nishioka stunned Nonito a couple of times when he opened up. (Salido & Garcia are killers) Besides... Danny's big brother is Donaire's trainer.
Garcia I'd make a slight favorite over Donaire. Salido is a favorable stylistic matchup for Donaire though. I think Donaire would beat him, but it'd be a very tough, close fight. They're both far more difficult fights than if he were to stay at 122 though, for sure.
Rigo, Most interesting fight, best opponent , has a title , easiest fight to be made due to same promoter
Donaire is The Ring champ along with the IBF and WBO belts, no need to fight Rigo for his WBA strap to prove anything. He just TKO'd the main man in the division!
Rigo is all hype. He has to man up and fight elite fighters first. He should stop fighting tomato cans.
Donaire-Mares is one of the best fights that can be made in boxing. (Assuming Mares beat Moreno which isn't a sure bet by any stretch)
