What if fight #3. Joe Frazier vs Ken Norton. Who wins?

I would pick Frazier without a doubt. As talented as Norton was, as big and as strong as he was, he just couldn't handle punchers. He was a nightmare for boxers like Ali and Holmes, but look what happened against big punchers Foreman, Shavers and Cooney, although he was slightly past his best for the latter two, he crumbled. Frazier would be the smaller man but he had relentless determination and one of the best left hooks in the business, I doubt Norton could take many of those lefts and would be out of there fairly quickly. Frazier WTKO2.
