Much more excited at the prospect of a Mares-Donaire bout, though I doubt that'll happen. That's the best fight to be made.
As much as people depend on Rigondeaux's skills to defend him, he is unproven at the top level. The argument that his chin didn't look great against mediocre opposition makes it worse.
Of course, if you are a fan, you are going to support your fighter. But from an objective point of view, Donaire is so much more proven. Subjectively, I can see Donaire winning by KO pretty early.
