Period : 2009-2011 before Gamboa moved up. Yuriorkis Gamboa vs Cristobal Cruz "Lacandon Cruz" Yuriorkis Gamboa vs Chris John Yuriorkis Gamboa vs Juanma Lopez Yuriorkis Gamboa vs Rafael Marquez Yuriorkis Gamboa vs Hozumi Hasegawa Yuriorkis Gamboa vs Johnny Gonzalez Yuriorkis Gamboa vs Celestino Caballero Yuriorkis Gamboa vs Nicholas Walters Yuriorkis Gamboa vs Robinson Castellanos Yuriorkis Gamboa vs Shoji Kimura Yuriorkis Gamboa vs Satoshi Hosono Yuriorkis Gamboa vs Elio Rojas Yuriorkis Gamboa vs Takahiro Ao Who have his chance on this list against the Cuban legend on the times he was a world champion in Featherweight ? (Of course I only count the top 126 lbs that Gamboa didn't fought in his career on his period).
I think I'd favour Gamboa against all, in one off contests. I wouldn't favour him to beat all in consecutive fights, though.
Only fighters I give a chance against a prime Gamboa would be John, Marquez, Gonzalez, and Lopez. Gamboa was an incredibly gifted offensive fighter but had some major flaws that's led him to being dropped constantly even during his prime. I think John had the ability to outbox Gamboa while Marquez, Gonzalez and Juanma had the power to drop and perhaps hurt him bad. I do miss watching a prime Yuriorkis Gamboa in action. Guy was very exciting to watch.
