Yes , if Basilio could then surely Duran could get a decision. I was thinking perhaps, maybe a small window post LaMotta title fight, late 51-early 52. Maybe, just maybe, Duran catches Robinson at the right time. It's an uphill battle and the stars would have to align.
This is an easy one. Have a fresh-as-a-daisy Roberto Duran enter the ring between the 12th and 13th round of the Maxim fight. I think Roberto of Barkley could take that Ray.
