Has the frame to go as high as 130 and could do 135 with the right development physically. It's about timing in this game and if or when he does move up he needs to develop body to help with his in ring attributes. I think he will have a successful career in higher weights.
I'd like to see him up against the Mares v Agbeko winner, then step up to 122 and take on Rigo and WV2. If he's successful there then take the step up to 126 and maybe 130.
If Agbeko beats Mares Donaire will move up right away and maybe fight Vasquez., If Mares wins he'll mop up at 118 and then move on.
5'6 guys are at 140. Donaire is skinny. Each person is different with how they carry the muscle. I never thought Pac could go to 154!
He'll beat Rigo IMO (sadly) Gamboa will crush Nonito at 126 if he's still around. Depends what he wants to do after that I reckon.
The problem with 130/135 isn't just physical, its the age that Donaire is likely to be when he hits those weights. He'll be in a bigger division AND probably in decline as a fighter.
High. It's all about having that explosive quality to be able to achieve these type of feats and Donaire is perfect.
