Jones would definitely beat Leonard while in his prime P4P and let's not forget that the Leonard that beat Hagler beat a fighter past his prime and Ray was nothing more than a blown up lightweight that left his best fight behind when he beat Hearns. Hearns had not matured as a fighter until he lost to Leonard and if he fought Jones who was a natural middle weight two things will materialize, Jones speed and the fact that his punches were so accurate. Let's not forget that Roy had trouble with lefties as far as Hagler is concerned, many people on this panel don't remember his Philadelphia wars. Jones never had one until Tarver. Someone mentioned the mongoose Archie Moore and I know Jones would have to be in super condition to meet a guy that had the knockout percentage Archie had as a lightheavy. It was over eighty percent even while he was defeated by some of his era's best heavyweight champs and fought Way into his forties. He was tough. Micheal Moorer was devastating yes but his opponents were not like the others just listed.
