8. ROBERTO DURAN
Title fights: 0-1
Summary: One of the most-accomplished lightweights ever had his last great moment at 37, when he outpointed heavily favored Iran Barkley to win the WBC middleweight title. He lost it to Sugar Ray Leonard at 38 on a near-shutout decision in next fight and would never again hold a major title.
Duran continued to fight until he was a month shy of his 50th birthday. And while he lost his biggest post-40 fights – including one that would’ve given him a title in his fifth weight class – he was competent.
His most-impressive victory probably came in a rematch with still-capable former middleweight titleholder Jorge Castro at super middleweight in 1997. And he lost his only post-40 title shot, a third-round knockout against WBA middleweight titleholder William Joppy in 1998, when Duran was 47. Beyond that, his victims were largely journeymen as he continued to campaign in hopes he would earn one more big payday that never came.
He did make a few dollars in two-fight series against Vinny Pazienza and Hector Camacho, losing all four fights be unanimous decisions.
