I've heard Quartey was pretty good, but could he beat Juan Diaz or Michael Katsidis? Who knows? I do think Marquez would put his jab and tighter guard to good use here and outjab this Quartey person to a wide decision.
This. I think Marquez has the clear advantage in power here. Definitely a more powerful right hand on the part of Marquez.
Quartey doesn't have as good a jab as Marquez nor did he ever fight a fighter with a jab as good as Marquez's.
