What did you see was old about Marquez? Marquez was juiced to the gills and his performance was outstanding. The guy was throwing concussive shots behind some serious force. His speed was up and his stamina was incredible... absorbed a beating and had more than enough to throw a warhead like that. Marquez went on to look as good as he ever has against Bradley and Alvarado (see him blast a 160 pound Alvarado halfway across the ring).
I totally disagree. Number 4 was the most violent of the saga.. you thought Whitaker at 33 with 1 loss and P4P no.1 was faded... just saying
