I still feel like some people don't give Barrera enough credit for his last two matches against Juarez. In the first fight Marco had to readjust and focus on fighting Juarez after he had been preparing to go up in weight to fight Chavez. He gutted out that first fight and showed his heart. In the second fight he put on a boxing clinic and showed what a master he is at adapting from fight to fight. Say what you want about Juarez...but he is a young, very strong and accurate puncher. Marco fought him once and gave the younger fighter a rematch immediately. Barrera is a great champion. But his fight with Marquez will be as difficult a challenge as he has ever faced. Marquez might not have the same resume as Marco...but there is no questioning he has tremendous skill and against Pac he showed tremendous heart. This should be a great fight.
