Oscar comes to mind for me. He ued to have very good footwork but now he doesnt use the ring as well. Most past prime fighters can move like they used too but only do it in flashes cause there legs arent what they used to be. They want to move but there body cant do what the brain tells it to do. Jones, Ali of course, and true Mayweather doesnt move like he used too but mostly cause he fights a bit lazier than he used too because he can get away with it with his skill, reflexes, and timing.
