If this rematch was made quickly, after their first encounter, I would pick Marquez as the winner but too much time has passed now, and Marquez is getting older and possibly ring rust has begun to play a big factor. Marquez should have taken the fight the first time Pacman's team offered it to him. Yeah the money was not too good, but he was still fresh and still hungry for revenge. I pick Pacman by knockout in the later rounds.
