Hopkins I've always thought would've beaten the 2002 Roy Jones Jr. Hopkins was still a mover at the time and had great defence with some pop on his punches and would've broken down and nutralized Jones speed with this his tremendous foot work alone. Wathc the Hopkins vs Trinidad and Hopkins vs Antwun Echols fights and you will see this version of Hopkins was too dangerous for Jones. I'm a Jones fan but 2001-2002 Jones in no way beats Hopkins from 2000-2002 and that's why I believe Jones never took the fight at that time and waited so long until he knew he was too shot to win.
I would strongly favour Jones to win that one, but dont think Hopkins would get stopped. I would pick Jones by clear decision, but I dont think Hopkins would get hurt too much either
BHop would want RJJ to come out aggressive. Hopkins wouldnt have to chase RJJ then. 2002 RJJ would beat Hopkins, clear but close type of affair.
