Gamboa, where do you put him p4p?

gamboa fought a lesser opponent in his last fight....i remember manny challenged barrera on the start of his career in the US...i believe if i'm not mistaken, its right after winning the ibf belt from a south african. barrera i think is just his 2nd bout on US soil and its the most dramatic victory i ever saw in boxing, a standing tko on the last rounds, very rare....gamboa should do the same.....
