Its different - I think those guys have thudding power and are probably bigger hitters being naturally bigger men. They can probably hit a spot on a bag for example with more power and force than Oscar. But that isn't what necessarily hurts a fighter. Plus Chavez did still hurt Sergio.
I have always felt Sergio was vulnerable though and I think Oscar is a sharp, accurate, fast puncher who can set traps, land counters, or powerful leads. That is why I see him hurting Sergio. He may not finish him off, Sergio has a big heart, but those moments would probably be enough to at least swing the fight in his direction if not lead to a stoppage of Sergio.
