I know people are going to jump on me and say Manny of Floyd would have stopped him at any time in his career. And I agree, I think Floyd or Manny beat him 10 out of 10 times, but I dont know that he would have been knocked down from some of the punches that were landed. He never had a good defense, but he had a sturdy enough chin that he could take punches to land punches, though not without a price. Over the last few years it seems he was getting buzzed more and more since around the Maussa fight. That was his 40th fight in a career that he built on the ability to walk through punches when needed and finishing the job. Maussa and Tszyu, both big puncher, rocked him in their fights but never put him down and his head seemed to clear faster than recently. So my question is did his ability to take a punch diminish over time, or was it that he just didnt fight good, prime opposition until late in his career? Or was the weight gain and loss a factor? I suspect its a bit of all these things combined. All in all, I do think there was a time when he had a very good chin. With his style, he wouldnt ave made it this far without one.
