At 130 or 135 i pick Hector with a chance to Roger. At 140 i think Roger would stop him. Roger was a monster at 140.
The Ramirez version of Camacho was a better boxer than Mayweather IMO and had more talent, speed and power. I'd pick him to UD Roger in a competitive, but clear win.
Highly doubt that. If Trinidad, Oscar or Chavez couldn't do it, Roger would be the last fighter to cross my mind to stop him. He had a very good chin and after the Rasario fight, he became one of the best survivors ever.
