Joyi is very limited IMO. As far as a skilled boxer-puncher goes he is decent and he is massive for the weight and very physically imposing. He lacks the dimensions of Gonzalez's game. Gonzalez to me is a very watery fighter, in the fact he is very fluid and adaptable but pours on the pressure. I'm thinking Joyi will be moving up soon anyways, the guy is the size of a Bantam. I think Calderon definitly deserves a mention here, as for my money he is probably the most skilled fighter behind Lopez at the weight. But Minimumweight has always been odd, where it gets fairly long-reigning champions who in relaity are just decent fighters and the true top-class guys like Lopez, Gonzalez, Calderon etc... really expose these guys and rule with an ironfist, although they are few and far between. What about Rosendo Alvarez? He's a fighter I very much like, aggresive boxer-puncher sort of style but in all honesty he is very hard to classify to a style. But he gave Lopez hell and was one of the best Minimumweight champs.
