andre ward- allan green i remember one round where the comentators said green didn't even throw a punch.
Bowe-Golota II. Even though Bowe fought back once in a while and scored a KD, Golota beat the cr** out of him for most of the time...
ali-frazier II was actually as rather uneventful fight, more of a boxing clinic. no beat down there lacy vs calzaghe comes to mind
