Was there any fighter in any era of the Strawweight/Light Flyweight/Flyweight division who could have beaten Finito? As great as he looks on video I think there's a handful of top tier fighters around his weight that could have solved his style. Lopez was not as perfect of a fighter that everyone claims. I think Roman Gonzalez has the style to beat Lopez IMO.
Ivan Calderon, Michael Carbajal, Chiquita Gonzales, Johnny Tapia, Marc Johnson, Luis Estaba, Chocolatito, Miguel Canto, Orlando Canizales, Kwang-Sun Kim, Paul Gonzales, all would have been tough fights for Lopez, i'm not saying any of these guys would have beaten him, but any of this guys is an easy fight.
No worries. He often gets ignored in the mix, but I kick myself seeing the names at 112 or below during their day and none of them came off, minus Gonzalez vs. Carbajal that is. Had 105 and 108 not been added, flyweight would have been loaded.
I honestly think that the only ones who would have posed some serious problems against Lopez besides Chocolatito are Jung Koo Chang, Mark Johnson, Yuri Arbachakov, Hilario Zapata and Miguel Canto.
