In a battle of Duran's two best lightweight victims. I think Kenny was better and would win a comfortable decision.
I think I'd lean toward DeJesus. I think he was comparably fast and skilled as Buchanan, but also a sharper, harder puncher. Plus Buchanan had a bit of a tendency to get drawn into inside exchanges, and I think DeJesus would have the advantage whenever that happened. Tough to call either way IMO, since Duran pretty much prevented either of these fighters from demonstrating their full potential.
