I respect Mancini. Who doesn't? He was tough, he trained hard, and he came to fight. But at his best Rosario was a frightening opponent. Too powerful for Ray.
The Rosario I saw destroy Elizondo like he was a jobber, yes to Mancini being in trouble. Rosario comes in less than that then he isn't icing Mancini quick and hard. In a war of attrition, I'd go with Mancini.
