Arguello is my all time favorite. However, in a 12 rounder I'd have to give PBF the nod to win a close, but clear decision. If we give Alexis 3 additional rounds to get the job done, he'd stop Floyd, possibley while behind on the cards. This has nothing to do with PBF handling 15 rounds. He trains like a lunatic, and would have made a fine 15 round fighter. However, we just gave a man who generally OWNED the championship rounds 3 extra rounds to find a home for that patented right hand.
Both guys were at their absolute peaks at 130, and probably among the very best ever at this weight. Both guys pose stylistic problems for each other. Very tough to call. Could see this playing out a bunch of different ways.
Arguably the two best EVER at 130. I've argued for years that it comes down to the difference between 12 or 15 rounds. Alexis needs those last 3 rounds. Floyd would be better off without them.
