Honestly the more I think about this after watching some youtube last night I think Arguello stops him.
They don't come braver or gamer than Morales ... his heart is unbelievable ... however the jump in class to the murderous punching Arguello would end in defeat ...
Yeah, this, just as Chacon, Limon, Escalera did. Arguello would get to Morales eventually, even if he has bludgeoned him for rounds on end and only got more resolve from El Terrible. Guaranteed action fight, but Arguello is better at pretty much everything than Morales.
