Joe had two good healthy hands when he beat Eubanks and would have wiped Collins out at that time. However he was inexperienced and was tired after round 4. He was more experienced when he fought Kessler and Lacy but not as hurtful a puncher. He was crap during his fights with Starie because he had an elbow injury but livened up when he blasted Sheika.So the answer is don't really know.
