Frank Bruno V Joe Louis?

Joe Louis without a doubt. I don't want to knock Bruno because he was a nice guy, but he would be out of his depth vs Louis. Bruno was a big, powerful fighter but wasn't as skillful as Louis and his one big shortcoming was that he couldn't take a punch very well. Louis was one of the hardest punchers in history, and unless Bruno could take him out with a lucky punch very early on- and I doubt he could- Louis would chop him down with his trademark hooks in within five rounds.
