Come to think of it Barrera, Morales, Corrales, and Castillo never had a shot at each other. Morales had his trilogy with Barrera and who could forget Castillo-Corrales I & II. I know Morales-MAB were at 130 and Castillo-Corrales were at 135. But these four would have made great fights with each other.
Castillo from the Stevie Johnston fight would have beaten MAB. MAB is a great fighter, but Castillo is a good and bigger fighter. Castillo over Morales Castillo over JMM.
I wont call you crazy but I disagree. His best chance would be against the smaller Barrera but Morales and Marquez, nah. Would be some entertaining scraps though.
