Duran would have given JCC a fit. JCC did not really have a plan B in his career. It was come forward and destroy. He had great defense, the kind that takes the snap off people's punches. He could give you angles while coming forward, which has not been performed well by a lot of fighters. And, JCC was as we all know, a devastating body puncher.

Duran changed throughout his career. He learned how to handle the biggest punchers, the slickest boxers, the warriors, and flat out some great competition. Note that, Duran's only trial at lightweight was Esteban De Jesus, who Duran destroyed 2nd time after claiming stomach cramps in their first fight.

If JCC can't hurt his opponent, he can't win. Duran would find a way to beat JCC.
