Im not going to definitevly say it was but I was watching Duran-DeJesus III again the other day and Roberto was just straight up T-101 in that fight, excellent display.
I don't think I've ever seen a better overall fighter than Duran that night, perhaps his performance in Leonard I as it was against a higher caliber fighter, but he did everything against DeJesus, he was so dominant that night.
I agree it's probably Dejesus III, but the Buchanan fight because of Duran's age and the caliber of the opponent is right up there too.
Fights 1 & 2 with DeJesus were great / vintage Duran...... Ray Lampkin getting KO'd late was also good... MR.BILL:rasta
