Pernell Whitaker by UD he beat very good pressure fighters like. Azumah Nelson, Jose Luis Ramirez, Julio Cesar Chavez, Jorge Paez, ETC.

And for the person who said Pernell Whitaker would make it a track meet, have you seen Pernell Whitaker at Lightweight ? he could easily throw 100 punches a round and would often stand his ground making you miss and making you pay.

Roberto Duran did beat some underrated boxers at Lightweight like Vilomar Fernandez, but i don't think he ever really beat a great fighter at Lightweight. Esteban De Jesus was good but not great. Ken Buchanan is the only one but even that had some controversy.

Roberto Duran had very good defense for a pressure fighter, a steady body and head attack. Aswell as cutting off the ring good, but he could be outboxed.

And i think Pernell Whitaker with his great angles, footwork, speed, elusiveness, would be able to win a close UD.

And remember Pernell Whitaker had underrated toughness aswell, he got his jaw broke in the 2nd round while past his prime vs Felix Trinidad. And he still made it too the 12th round.

There's a reason Pernell Whitaker has never legitmately been stopped, and thats because aswell as a great defense. He had underrated toughness.
