How long was the reach of Gilberto Roman? He seems quite short,stocky and not that long of an outboxer,but had very beautiful boxing abilities. Then you can count on Betulio Gonzalez, Venezuelan and a bit more versatile Canto.
Hmmm,if Roman can't work out... Then Alberto Davila,never too talented but skilled enough to compete in world level. Miguel Lora seems quite small and short,yet he has a very good defense, although I might still need for someone to explain how good is his outboxing game. You also have Greg Haugen who recently passed,might not be a full fledged boxer but has a short reach and never truly pressured with his head on his opp's chest,so why not? And lastly, Melchor Cob Castro as a honorable mention.
