Calderon IS the best fighter below 110 lbs. i think he has the skills to take on anyone, out of all the BOXERS to ever come out of Puerto Rico i'd say he's in the top 3 at least in the skill department, 1.Benitez (a boxing god, and IMO one of the greatest welters ever), 2. Camacho (even though he didn't live up to his potential his skills were undeniable), 3. Calderon (the small latino Mayweather)
