Duran would have trouble getting past Oscar's jab and the power DLH had at 147 would keep him humble. I see Duran being frustrated and quitting mid-late rounds. Otherwise a UD for DLH, imo
Duran at his best wins ODLH was like a lesser version of SRL. Duran could be hit and miss above Lightweight, but since we're matching both fighters at their best. Then the version of Duran that beat Palomino, SRL, wins this.
Uh, he got past Ray Leonards jab, no problem. He'd get past Oscars and if you thought Tito was after him wait till Roberto's in his grill.
Duran beats him, Oscar isn't Leonard, he's easier to hit than Leonard for a start and would fade late unlike Leonard. Oscar also had a bad habit of choosing the wrong tactics and being drawn into the wrong type of fight, too passive vs Tito, too aggressive vs Mosley as examples.
