Pedroza most likely beats up Lopez in one sided fashion. Just too versatile, tricky, and gifted for Lopez. Although I will say that Lopez does have a puncher's chance in KOing Pedroza in the same way that Zamora did.
Pedroza would be considered the favorite (although in real time, if it had happened, he wouldn't have), but one thing to consider is that Pedroza never fought a guy who was as hard a puncher as Lopez AND as tall as Pedroza, who usually used his size well. Lopez presents a unique physical challenge that could be difficult. Little Red is my all time favorite, so I'm biased, but this could possibly go to Lopez even if Pedroza is the likely winner.
That's almost impossible and stylistically Sanchez is as bad as it gets for Lopez. Pedroza wins but he won't hit Lopez as hard or as often as Sanchez did, might go to the body for though.
I remember Pedroza from losing to McGuigan, but he had a lot of title defenses and beat some top fighters. He was tall for a featherweight and could box. He was KO'ed three times early on in his career, but still went on to be champion and makes several defenses. When he hit his stride, he really hit it. Danny could punch but also took a lot of punches too. I guess he'd have a puncher's chance, but I'd have to go with Pedroza by clear decision.
