I actually think Barrera had one half of a great fight plan in his rematch against Pac. Marco's movement and defense made Pac miss quite a bit in the fight. But he obviously no longer had it in him to let his hands go. In retrospect...i think Barrera's last great effort was his fight against Marquez. He didn't have the heart and offensive sharpness against Manny. If Marquez can remain sharp and hungry...i can see him countering Pac and winning a tough fight on points.
