Virgil Hill (broken Ribs) Glen Kelly (1 right hand) Montel Griffin (1 left hook never been Ko'd) Art Serwano (looked like he was dead) jorge Vaca (1 left hook) Although I do slightly agree that Jones don't have the pure raw power as the guys listed above. Jones power came from speed and punches that where not seen.
Julian Jackson did not have more power than RJJ at Middleweight. If you want to talk about P4P at JR. Middle then yes, but not at middle.
