The only 3 Lightweights i give any chance of success against Duran would be

Arguello
Whitaker
Mosley

I believe Carlos Ortiz would have been a handful for Duran in his prime.

I think prime Duran beats them all, however let's not forget how well Esteban De Jesus went against Duran in 3 fights, all of the above mentioned would give Duran trouble. De Jesus would have been a difficult opponent for those guys as well.
