Chavez vs Duran @ lightweight, both in their prime, 15 rounds?

Duran would've won the first five rounds by simply outworking Chavez, because he started fast and Chavez didn't. Next 5 rounds would've been a war with both men giving and taking big punishment. Rounds 10-15- Chavez fades while Duran keeps up his torrid pace and wins at least 3 out of the last five rounds. Duran wins at least 9 rounds and the fight.
