Donaire - Rigo is ripe with all the side stories going on between the camps. It's a headier, more tactical match up that would unfortunately interest only boxing fanatics. Donaire would provide the name to sell that fight.
The match up that needs to marinade is Donaire - Mares. Mares needs to beat a really good named opponent in his next fight to make the Donaire match up irresistible even with the promoters in the way.
It will be a superfight I would love to pay for.
