Pick your own weight class but how do you see these two facing off against each other. I tend to think Marquez was just a slight superior to Azumah and would eek out a close points win.
The Nelson that beat Gomez, has the speed and skills to outpoint Marquez. If the fight was fought above 130 though I would go with Marquez.
I'll take it a little further. Azumah wins handily at 126 and 130. Above that, Juan is better suited for those weights and takes control.
