You mentioned RJJ.
He was special when he was free to be special. timing shots and moving in bodily with a shuffle made him even faster than just his hands. I think Roy was so relaxed and at ease with his own feet to get him where he wished; he was able to study his opponents reactions to a move, then he wouldset them up for it and the next time throw a sort of tracking shot that would follow the path of the target (or ending where he knew they would go to).
