Chico had very short arms for his height, something I noticed specially in the PBF fight when although he had the height advantage, PBF had the reach advantage. Im not sure but I wouldnt be surprised if they both had the same recorded reach.
MAB was at his peak at Feather not Super Feather. Anyway I would pick him to use his boxing skills against big punching Chico. MAB has a better boxing brain and Chico was drained at 130, he was a much better lightweight.
At LW this is a no contest. Chico does indeed beat MAB quite easily, though if the best MAB turns up I doubt he gets "destroyed". Probably get KO'd in the 9th though. At 130 though, MAB holds a better resume and isnt at that big weight disadvantage.
Corrales tall lankey with good speed and power not to mention a very good defense, it would be an awesome fight but Corrales UD. I really miss Corrales. R.I.P. Diego Corrales
